It has been our experience and that of most our customers that Fleece Pouches can be comfortably worn in temperatures up to 90 degrees, in lower humidity, and 80 degrees in higher humidity. Most people choose to wear their babies inside where the temperature is controlled during the warmest days - such as at the grocery store, the mall or in your own home.

How wearing a polarfleece babysling will affect you will depend on a variety of factors. Including what activities you'll be doing while wearing your baby - will you be gardening, taking hikes or mostly wearing your baby inside your air conditioned home? Will you be wanting to use your pouch when running errands and going from one extreme temperature (the parking lot) to another extreme temperature (the freezer section in the grocery store)? How old is your baby? Only newborns and small infants are more affected by the warmth of the polarfleece as their entire body is inside of the pouch. Older infants and toddlers, on the other hand, have the majority of their body outside of the fleece. What is your normal body temperature and that of your baby's? If you are typically always "cold", then the fleece should be fine. If you're typically always "warm", then it may be too much for you. Do you have air conditioning inside your home? If not, the fleece may be too warm for you. What is your climate like? Do you have short periods of heat and humidity (less than 1-2 months each year)? Then, the fleece pouch will work wonderfully for you for the majority of the year. Stick to the indoors during the hottest days or use a cooler sling.

Therefore, most of our customers have been able to wear their babies year-round in their Fleece Pouches. Polarfleece is a unique fabric which breathes well, wicks moisture and will not overheat you or your baby if you are both dressed appropriately. While we do not recommend exercising with your Fleece Pouch during hot weather, general day-to-day activities are perfectly reasonable.

Personally, our last 2 babies have been born in March and May and we used our Fleece Pouch throughout the summer. In fact, it provided great comfort while shopping the freezer aisle at the grocery store!

However, all people and all babies react differently to the heat. You know yourself and your baby best. Below are some quotes from our customers, based on their unique experiences.

We have used the KK pouch since birth, and Andrew’s always loved it. But recently, I have found that he gets very fussy in it when we are in a mall (i.e., where it is warm). He gets too warm in it very easily, I’m afraid. The last time I was in the mall with him, I stripped him down to his onesie, and made sure that his arms were out of the pouch, and that helped a lot. Of course, what was best was taking him outside into the Scottish winter – then he LOVED being back in the pouch! And he never fusses in it when the weather is cooler. I have learned to dress him for the temperature of wherever we are going (i.e., the few times we’ve taken him to the movies, I always dress him in a summer outfit (with a coat on when we are outside) even though it’s winter, as I know that the theatre itself will be warm). ~ Carolyn and Andrew from Scotland

I just had to post about how much I am enjoying my KKAFP. My only reason for getting one was my obsession w/ slings/carriers. I live in an area where it never gets really cold. I was thinking fleece would be way too hot!. And, I assumed a pouch wouldn't provide a secure carry. Boy, was I wrong! My son prefers this pouch over any other carrier I have. The fleece is super comfy, and the only time I do not use it is when I am outside for lengthy periods (80+ degree weather). I have found it it be very comfortable for myself in comparison to unpadded slings. I just love it. If you live in a warm climate, you can still use a fleece pouch! I just can't get over how comfortable it is. ~ Jamie and Braden, 1 year, from Augusta, GA

I bought [the fleece pouch] when [my daughter] was about a year and a half and we used it when she weighed 35-39 lbs (she's a big girl). We live in central costal NJ where we do have hot summers. June thru Sept is about 85-90 average. Temps range from 75 to 105 and it's always really humid here. April and May run about 55-65, as does October. I had to stop wearing the pouch when it hit about 70-75 out. It was just too hot. Lauren got hot and I'd take it off and my shirt was soaked so badly I just had to go home and change. It was just too much. I really liked the ease of the pouch and that it's more compact than the sling but it's just too hot for summer use here in NJ. I have to say that I've been debating between buying a KK sling or a pouch that that's what swayed my decision to the sling, that I can use it in the summer. Obviously when it's 95 out, babywearing just isn't a good idea but there are times when it's not too hot for babywearing but too hot for the fleece pouch. ~ Stephanie from New Jersey

[I live in] Houston Texas. It is very hot and humid. Like well over 90% and with the heat index it's over a 100 Mid June-Sep. [My baby] was born last April and we got our Fleece Pouch in mid Jun right before we went to Sequia National Park in California. It was very hot there too. I went hiking and everything in the Pouch, he spent about 18 hours a day in for a whole week. It was very cold in the evenings and the Pouch was like a blankie so he did not have to bundle up. I wore him in the hot humid Texas heat all summer long with no problem. It wasn't really any hotter than simply holding a hot sweaty baby. This winter I have appreciated it most. I don't ever have to bundle him up in a bunch of layers, hats, coats not even socks. Just pop him in the pouch and it can cover his whole body while I get him in and out of the car, store, whatever. We even went to Oklahoma last week where it was snowy and I still didn't have to bundle him up. My 3yr old even enjoys it when he is tired, sick or just wants to feel equally special as his baby brother. My experiences have only been good. ~ Angie and David-Aaron, 10 months, from Texas

[We live in] San Luis Obispo, Ca. It's on the Central Coast. The summer here is 2-3 weeks long and never hits 100 degrees. It's always breezy and windy since we are near the ocean and gets very cold after sunset. I love my Fleece Pouch. I love to wear it at night because the baby keeps me warm and is easier to see if we are out in the dark rather than let her walk. I found that I get hot if I wear it while really active like walking around the mall for hours on end or if I am in a rush and I am already hot. It is by far the easiest "sling" I have tried and really does distribute weight well for me. I have people ask me all the time where to get one and how it works. I think for my climate the pouch will be good to use all year long. ~ Lindsey and Rylee Breanne, 1 year, from California

We live in Maryland where we have 4 very distinct seasons: freezing in the winter and then hot and humid (90+) in the summer. (Of course, then there's the in-between weather in spring and fall.) I used my pouch last summer in 90+ degrees with my youngest son, who was then 2-4 months old. Honestly, I used it mainly in the evenings to take walks with the 2 younger boys while dh and oldest son played tennis. While it was a little "warmer" wearing the pouch, I was so delighted to have a comfortable way to carry my baby and FREE HANDS for my then-3-year-old that I really didn't mind being a bit hotter. We took some pretty lengthy walks and it was very comfortable for me. As for the little guy, he slept through most of these walks and seemed to stay very comfortable himself. A few times he got a little sweaty, but honestly not much more than he would have if he had not been in the pouch at all. The fleece DID seem to wick the moisture away from him. I think most people just panic when you combine fleece and summer in the same sentence! Not that I'm an expert by any stretch of the imagination, but it seems to me that wearing ANY sling in the heat of summer is going to be a bit more uncomfortable than not having any extra fabric on you. Of course, I didn't actually have him out in the pouch in the middle of the day, so that may have been a different story. I'm VERY anxiously awaiting the arrival of warmer weather and plan to use the pouch for more walks with my youngest. Of course, I don't think it's going to be the heat of the pouch that shortens the lengths of my walks---I think it will be the weight I am carrying! (He's approaching 25 pounds now.) Thanks again for all you do! I love just browsing around your website---I find it very relaxing and encouraging. ~ Carrie from Maryland

I live in Ohio and it gets down to below 0 in the summer and over 90 w/hot humid muggy days in the summer. I LOVE my fleece pouch. My son was born in July and its was a HOT humid July too. It is extremely comfortable to wear and doesn't hurt my back or neck carrying him. One problem was that the pouch is a little deep and with him being a newborn, he would fall into the pouch and with it being so hot, he would get all sweaty. As long as I kept a receiving blanket folded up under his head/torso area so that his head was above the pouch, he was just fine! He loved being in there and slept so well I got tons done around my home while he was in there. As he has gotten older and bigger, I felt that he was outgrowing the pouch and was disappointed. Then Tanya told me how you can wear older babies a
different way and they don't use as much room as newborns do in the pouch and once again, the pouch is a life saver! So I have used it in 90 degree humid weather on a walk and in freezing weather in the winter and am ready to do it again this summer with him. I love this pouch! ~ Gina from Ohio

[We live in] North Carolina. Summers can get pretty hot and humid here. From April into Sept/Oct. we have a lot of 80 plus days, hottest summer gets into the 90s with humidity and lasts July/August. I used my pouch with my newborn last summer. The pouch was fine for air-conditioned homes and stores. If I carried her outside, to the park with my preschooler or even from the car to a store, she often got sweaty. I would usually carry her by hand into the store, and then put her in the pouch when we got in the store. I took her for walks, early morning or early evening with my son. I wore her in the pouch, and cut the walks short because she often seemed too hot, even when I folded the edge of the pouch down, exposing her head and face as much as possible. Her hair would be wet, stuck to her head ... looking back, I wish I had had a cotton sling for carrying her outdoors in the summer. Looking ahead, I just made (yesterday, actually) a cotton ring sling for carrying her in the upcoming hot weather here. I'm not as concerned about the fleece with the hip carry as the cradle carry and other carries where the legs and feet are tucked in. I think with her on my hip, much more of her body will be outside the pouch and she won't get as hot as she did when she was tucked in there as a newborn. but I think the advice you gave me before I bought my pouch was helpful and proved true .... for inside air conditioning, the pouch is fine and you really don't spend a lot of time outside when it's so hot anyway. But for the times you are outdoors ... from my experience, the fleece was too hot for carrying a newborn in the summer heat. as for the spring, fall, winter ... the pouch has been wonderfully compatible with our weather. We are pretty mild here, even in the winter (lots of 50s plus days). Our pouch often doubles as a jacket for my daughter. she stays plenty warm in there. Plus the pouch helps keep me warm so I can often skip a jacket when we're out. ~ Amity Page from North Carolina

What can I say except that you are doing an awesome job with your slings and pouches!! And your POUCHES!!! Oh my.. I love them! (Doesn't everybody?!?) I live in Singapore (a hot tropical climate) but I have them in a variety of colours. My older son never got to use it, but my youngest absolutely adored it.. (as did I). I live in Singapore. We are an island on the equator and it is a hot, humid, tropical climate all year round with temperatures ranging from 26 - 32 degree Celsius. (I think that may be in the 80s in Farenheit terms!) I absolutely love my fleece pouches for their convenience, comfort and ease of use (just slip on and go) - for both me and my baby. My son, Kaden, was always so happy in it because it was so snuggly! I loved carrying him in it. The only thing though.. because I live in such hot, humid weather, it was impossible to use the pouch outdoors (mainly because of the humidity - we would both get too hot and sweaty with the pouch on!). But because we're indoors in air-conditioning mostly (in malls, office buildings etc), I actually managed to use the pouch quite a bit (even though sometimes we had a tendency to get too warm e.g. if the air-conditioning wasn't on high enough, or if I'd carried the baby for too long and our body heat would start to warm us up a bit). For outdoors, I would switch to the unpadded sling. The pouch is perfect for traveling though (to cooler climates and on planes!). Practically, I think it would probably be better to go with an unpadded sling in our type of weather. But because I love the pouch so much, I always took it out with me and used it in malls and air-conditioned areas. Perhaps it would be better also if the temperature were hot, but not so humid! I don't know if this is any help at all, but I haven't had any really bad experiences using the pouch. If I felt we were getting too warm, I would simply take the baby out so that we could both cool down a bit! Thanks for providing us mummies with such a wonderful tool! ~ Annabelle from Singapore

[We live in] Livermore, CA (East of San Francisco). It gets to 103 here in the summer and is dry, not humid. I just got my pouch a month or so ago, so I haven't experienced it in the super hot, but we did go for a 5 mile walk in the 80s and I just got her naked (well, with a diaper!) and put her in the pouch. We were both a bit sweaty where we touched, but it wasn't too hot. Around here, all the stores are FREEZING when it's hot. They turn up the air way too much, so I can't imagine shopping to be an issue. At home, we don't have air conditioning, but I probably wouldn't be holding her when it's that hot anyway. I think of the pouch as an extension of my arms. So if my arms would be too hot, then the pouch doesn't really come into play! ~ Debbie and Signa, 6 months, from California

I'm from Toronto but I am currently living in Costa Rica, Central America. I purchased a fleece pouch from you a few months ago. I brought the fleece pouch here hoping I could use it but found it to be way too hot. It is currently the dry season here in Costa Rica and it gets pretty hot. Temperatures are in the 34 c + range, I'm not sure what that is in Farenheit. I was using it for awhile at night but March is the hottest month and I have been using my unpadded cotton sling all the time. My baby is just about 7 months old and we mainly use the hip carry. I also brought our baby trekker but find it to be way too much for this climate. I was hoping to use it for hiking but again I switched back to the unpadded sling. Anyway, the fleece pouch is great but for this climate it is too hot. The unpadded sling works great for me and I use the open tail to protect my baby from the sun. The women here carry their babies in sarongs much like a rebozo. They take 2 sarongs and cross them in front and tie them in the back and sit the baby in the front, just like the front cross carry for the didymos but with 2 pieces of fabric. They are all amazed by my sling because it is so easy to adjust. ~ Billie-Jo and Jasmie, 7 months, from Costa Rica

[I live in] Sunny Central Florida! Humid and HOT! Today was the first time we've used it outside for a long period of time. We went to Sea World and we used it quite a bit! The temp outside was humid and hot, but not that bad for Florida. I had Noah in the cradle carry for a few minutes waiting in a line, and when we got inside he nursed while in the sling and I needed to change his diaper after that. I noticed that he was sweating (he had a onesie, and jean shortalls on w/ a diaper), so I changed him into cotton shorts and a sleeveless tee shirt. He was perfect for the rest of the day! ~ Devin and Noah, 6 months, from Florida.

I live in NYC where it gets to be very hot 80-90 and muggy 100% humidity in the summer. The pouch really is wearable in the summer but you have to break it in first. What I found is that when you first get the pouch, it is very fuzzy and warm which is great in the winter but then it kind of wears away and doesn't feel as warm. I would recommend people buying their pouches in the winter and enjoy the coziness and by the summer it will be worn in enough to be comfortable in the heat. The truth is though on very hot days, I would probably choose my maya wrap or mesh sling over the fleece pouch even when it is worn in. I have a 5 month old and a 2 1/2 year old. I hold both in the sling. ~ Chaya from New York

I live in Vermont. Winters are cold and summers are hot, last summer, was up in the 100s, but I think that was odd for up here. 90s are more common. It gets humid. I get 3 seasons out of the pouch, and the odd day in the summer when it is raining and crummy out. Once it gets up towards 70, it is just not comfortable anymore. I sweat, and my son sweats. Regardless, I use it exclusively for the other 3 seasons, so it is totally worth it. My son just turned one year old. I used it as he was a newborn and little guy in the winter and spring, and was able to come back to it this fall when he was 7 months. ~ Amy from Vermont

[I live in] S. California. Warm to hot all year. Coldest day temps in winter: low-to-mid 50s, usually more like 60. Coldest nights: 40s. Summer: upper 80s to 110. Typically low humidity but last year was more humid than usual. I use our fleece pouch all the time in the Winter months, November-March/April. It's great! I can leave my daughter's jacket at home. I have worn it on days in the 70s but once temps are 80 (whether in sunlight or indoors), dd gets too hot and sweaty in it. We have had some unusually humid days but even on low-humid days, in our experience the pouch is too warm for 80 and up. ~ Nancy from Southern California
