Large 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

This stuff is AMAZING. I have a ton of spinal issues and deal with a lot of pain. Heat therapy really helps me so on an overseas trip with a 16.5hr flight I took these with and put them on my back. Man did they help. They actualy heat up to where you can FEEL IT and they stayed hot for longer than the duration of the flight. I was amazed and so happy as they gave me relief to help get through the flight. They do take a minyte or so to heat up but once they’re hot they work great. A must have if you run cold and have constant pain and can’t always plug in a hot pad or boil water for a hot water bottle.

Gets just as hot if not hotter than the big name brand & lasts hours longer. I'll continue buying these instead for camping & body aches & pains from now on. Especially worked better for me when driving on long trips. 1 in the small of my back also got warm enough to help with my sciatica. 2 on my dealing with my bursitis & sciatica pain down that leg while driving. And kept me warm enough while camping that I didn't cramp & lock up.

I love this product. Not only for warmth but helps when my hands feel stiff. Just feels good and lasts a long time. I have re-ordered many times and always have them on hand.

These work great. I’ve purchased in different sizes. They do get very hot so don’t put them directly on your skin. They really do heat up. And lasted a reasonable amount of time.

The 18+ hour body warmers are a decent option for staying warm, though they don’t quite live up to the full 18-hour claim. In my experience, they lasted about 12 hours, which is still pretty good. However, I did notice that they work best when placed inside clothing or tucked into pockets. If I held them in my hands out in the open air, they didn’t seem to generate much heat at all. Overall, they’re effective as long as they’re used correctly. For outdoor activities or situations where you need consistent warmth, these are a solid choice and worth the money but don’t expect them to go the full 18 hours.

I've been using and donating this brand's hand and foot warmers for years. **Heat performance is spot-on** , not scorching, but the perfect steady warmth for football games, outdoor workouts, and cold-weather activities. They activate effortlessly, last the stated time, and deliver consistent quality, exactly what you need when reliability matters most. Bonus: these make a great donation item for people experiencing homelessness in winter. Just be sure you donate them to organizations doing active street outreach so they reach the people who need them most.

Great product and does the job

Love these! I have cold feet and I use one of these to warm them in bed at night in lieu of a hot water bottle or electric blanket. It stays hot all night. I hold it between my feet until they're warm enough and then just let it keep the area warm, occasionally resting my feet on it when needed. It can get too hot to have on your skin for too long, so just be aware of that. Already on my second box.

I have a herniated disc in my lower back and I was buying heat those wrap around your waist heat packs for it from the drug store. This is way more affordable and they stay hot for a long time, 16+ hours

this is an exellect heat source wherever it used ,hands,feet, or body

Going to put 2 of these on my generator before bed 1 carb and 1 on oil pan, tried it this year at -30C, 2 pulls and started with hand warmers, these are hotter and larger, should be perfect.

I use this product all the time in the arena and it works for 10 hours. Great size too!

Decent heat for about 12-14hrs.
