Body Warmers Large Size Heat Patches, Adhesive Heating Patches Disposable, Portable Instant Hot Packs Lasting up to 10 Hours, Travel Size Heat Pads on Cruise- 20 Packs

Hey these things are great! Get warm but not too warm -- and don't tear skin when removed.

I brought it to my Arctic trip, let's just say I can't thank this enough. It was long last and I used it mainly for my stomach during cramps and for my body while staying outdoors for mountain hikes.

These body warmers long-lasting heat. They're great for sore muscles and stay warm for hours.The adhesive holds well, but they do have some weight to them. The instructions say to affix them to clothing (you definitely don't want to put them on the skin). If you’re wearing looser clothing, they might shift around a bit, and not be close to the skin. They’re better for layering under snug-fitting clothes where they stay in place.

I should have read details. Cannot attach to skin! It is to be attached to underwear. My pain (leg) is not located where my underwear is! If I attached to outer garments, I doubt there would be any heat transfer to matter. I have not opened to test it or to try anything to make it work. I just want to return for my money.

I purchased a 60 pack, but I’m notice they will be ONLY slightly warm ( I mean slightly).. which it’s great for people who maybe very sensitive, I would have preferred they warmed more like the hot hands or something but these were like as warm a cup of coffee that sat out for an hour lol. - 6 hour warm

These patches are to be attached to clothing and the heat will dissipate when exposed to air, so ideally there will be another layer of clothing on top of the patch.Since this is winter and I'm using these on my back, they work great! I put one over my underwear and then put a long-sleeved knit shirt overtop that fits close to my body, so there's not much air flow to cool the patch too early.In warmer weather, I would wear a looser top so I'll lose some of the heated time.If I ever need to use one on my knee, I already own some elastic knee braces I could attach the patch too and then cover with leggings.For other body parts, you may need to get creative for how you will have two garments to layer under and over the patch, possibly using bike shorts, long sleeved undershirts, etc.

These body warming patches are very nice. They give off full heat for at least 8 hours, and then start to fade slowly. Mine lasted for about 10.5 hours. The heat is very warm, but not so hot as to be uncomfortable. They stick well, even if you move them around a couple times. I like that the size is big enough to cover a decent area but still small enough to fit inside my boots if I want to use them as feet warmers; I have very wide feet and most actual foot warmers aren't big enough for me. These are a great solution to that problem.
