UnderwarmerHeated Shirt, Compression Baselayer, 8 Built in Heat Packs, Body Warmer

Bought 2 for me(S) and my mom(M) and 1 for my son(L) - we had issues as was little snug but my son did not! So I’d say go up a size if female :) But it worked great! Started to get warm within minutes and really felt the heat after about 20-30! We used these for a Christmas Eve football game and it was -20 out! I gotta say, they helped tremendously! I will definitely buy again!!!

I really love this little vest. It does what it claims - keeps your core warm (but not hot). And, because the fit is snug, it doesn't show under clothing.Two things would make this even better:1) bulk purchase of two or more for a price reduction per item2) making an entry/exit for the warmers so that you can take out used warmers and replace them with new ones which, in turn, means selling these nicely shaped warmers separately

I was truly skeptical but now I am a believer!!! This thing is the real deal. It keeps you so incredibly warm. The forecast for the football game was high of 38 with snow flurries. We were also in the nosebleed seats way way up there and the wind was “supposedly” brutal. But I didn’t even need to wear a jacket. Just a shirt, then this vest then a sweatshirt. And was completely comfortable! And we were up there on the nosebleed seats! The wind was crazy! I was so warm! Other people had parkas and blankets and still shivering! Highly highly recommend!!! Our 5 and 9 year olds melted down by second quarter but not because they were cold. They were so warm! I would recommend not wearing it, infact, on your way in to the stadium. All that walking plus the heat from the vest made it too hot! It lasted a long time too. But they are snug so get a bigger size. If you are bigger than the XL size then I would just cut them song the seams and wear it anyway. Since you will be wearing a coat over it usually, it will be secured against you. Need to find a good hand warmer next. Heard so much about those rechargeable vests from friends who told me “only one side of the vest gets warm” or “the charge only lasts 1-2 hours”. These were toasty for 6+ hours and still going strong. I think the description says 8+ hours. You won’t regret it!!

Perfect for a cold winter Green Pay Packers game. Fit as expected and kept me warm for the entire game!

Bought these to wear to an NFL game that was in the single digits temperature wise. Glad I did! I would not hesitate to recommend these or purchase again. Great item for the price and definitely made a difference. I believe it would have been too cold without this vest. I bought one for my son as well and he said he could feel a difference with the vest. Thinking about buying a couple extra just to have in case!

Would recommend to anyone planning on being out in a cold situation any day. I used it for the panthers game in 20 degree weather under my north face and it did it’s job for sure. I wore it for at-least 5-6 hours and it stayed warm the entire time.

Material is not good

Wore these to a football game with the high temp of 18 degrees!! These kept us warm the whole game and were still warm into the evening hours!! Was a noon game! Definitely will purchase again. We could even take our big coats off and we’re still fine!! Very worth the money!
