Sport TempLarge Hand & Body Warmers - Up to 18 Hours of Heat, Super Long Lasting - Easy, All Natural - Air Activated, for Body, Hands & Toes - Odorless Hot Hand Warmer - Sport Temp

I ordered these for a Scout camp that was going to be near freezing the firt night. When I set up my tent I place two at the foot of my bag, one in the middle and one near the opening to preheat my sleeping bag. They made it more tolerable to get in the bag. Before I got in my bag I moved the pads so they were between my bag and sleep mat for the night. I was so warm, thanks to these warmers, woke up later on and had to move the warmers that were closest to my hips. Since they last 12 hours there was still enough warmth to them to keep my hands warm most of the morning, so I didn't feel I was wasting them. I liked that they were a bigger size than the Hothands I have used in the past. I highly recommend these and will purchase again.

I am a doc student living on an extreme budget in a place that is not exactly weatherized. I have a small ceramic space heater and wear layers indoors, but that doesn't always help. I liked these because I put them under the covers at the foot of my bed 20 minutes before bedtime. I couldn't be happier to be tucked in, nice and warm. What's better? They are larger and last longer than the tiny ones that fit in your winter gloves. So, I can get in bed, do some reading or homework, then finally go to sleep and not get cold in the middle of the night because the warmers wore out.I will keep these in my camping gear moving forward. I know they will be perfect in a sleeping bag. ;)

Arrived on time, and works, warms up the nights on our camping trips. We love it!

Took about an hour to warm up once activated but these last a long time. I went back to my coat a few days later and the pack was still putting off heat. Great size also.

Price is good and they do get hot but takes an Hour+ to get any warmth. I had to purchase a different brand for my baseball player to use because these take so long to heat up the game is almost over before there is any real warmth. Maybe it’s the larger size, and the hand size would heat up faster.If you purchase these, open them at least an hour early before use, maybe even 2 hours early.

Keeps amazing warm for a very long period of time. surprising and outstanding! Exceeded expectations.

So if you hadn't heard the news, we had a snowstorm in the South last week. And because here in the South we're not used to anything colder than 40°. I bought a bunch of these because I wanted to stay warm in case we lost power. So each night I would open a pack. We would stick it in our bed and when we went to bed our bed was so warm. These things were hot to the touch. But they made our bed so warm and they made us feel so warm as well. I highly recommend them. I was very pleasantly surprised.

These are great on cold nights out or for therapy. They heat up in about 2 minutes but once they're hot they stay hot for like 3 to 4 hours then start to lose their heat. But that's ALOT of time for a little hand warmer in my opinion. I like that you get a big box full of warmers and that's plenty for your uses. Really appreciate these little heaters, they keep me warm when everyone else is freezing.
