Ignik Resealable Multiple-Use Hand Warmers for 10 Hours of Heat Across 72 Hours

My experience with these things has been generally very good! The packets get warm but not hot, so they're not uncomfortable to keep in your glove or boot - though they are a bit chunky, so make sure there's room in your toe box before putting them by your toes. The reusability has been better then expected - While the packaging says they can be reused within three days (as long as you zip them up in the pouch when not in use), I have found they can still emit some heat even a week after there were originally opened. You just gotta shake them a bit.I would compare the warmth level of a freshly opened set to most other hand warmers, and the warmth of the week old set to a towel that's been recently pulled out of the dryer - pleasant but noticably weaker.Overall, these have worked well for me! They keep my hands warm in 40°F weather and I can put them in my pockets to bring the warmth closer to my core. I am glad I bought these! They're going to make camping so much nicer.

I was skeptical that these hand warmers could actually be reused, but if you use them for a few hours and then seal them back into their little baggy, you can re-activate them at least one more time, and I was able to reactivate one set a third time, although they didn't get very hot that time. The first time, they get quite hot. The only thing I don't like is that they take 10-15 minutes to start getting warm, so if you don't take them out prior to, say, heading to a trailhead to walk your dog, your hands are going to be cold for the first 15 minutes. If you do remember, they work well. I like the idea that they're biodegradable, or at least the interior of each packet is. Supposedly they can be composted, so I'll see what happens if I add them to my compost.

We got these hand warmers to keep our kids' hands warm while we go fishing. We live in the PNW and their hands get freezing during winter fishing. My husband likes them too. I like that each pack is resealable to be able to reuse the hand warmers in case you don't want to use both from the pack. It helps to save the other one from going to waste.

Doesn't stay heated long.

Went skiing in Colorado when temperatures were below freezing. This saves my hands. I loved the reusability feature. Also very happy to be able to compost/recycle them. It delivers a constant heat that is slow to start, but remains long and not burning hot. Definitely a must have in your ski gloves or ski jacket interior pockets.

These hand warmers work very well! The last for several hours! They kept my hands very warm when I recently went to New York. Great value for the money! Small enough to be portable. Just grab a few from the box.

Warm for a long time and can be reactivated.

These are great hand warmers. They need a 10-15 minute warm up period when removed from their pouch but then are very effective. The best feature is their reusability. I normally walk around an hour. At the end of the walk I put the warmers back in the pouch, close it, and they are ready for another walk that same day or a day or two later. Makes them much more cost efficient.
