For years owners asked us for a lunch-bag size, and this five-pack is what we built: 6.5" x 7.5" pouches, nylon-reinforced, with the same 18°F mix as our cooler packs. Line the sides of a lunch box and there is still room for the food and a drink. Flight crews, nurses on long shifts and parents packing bottles all tell us the same thing — the pack is still firm when the break finally comes.
Why this pack
- 6.5" x 7.5" x 1" — the size of a sandwich, made to line a lunch bag
- Same 18°F mix as our big cooler packs, in a pocket size
- Soft before freezing, so you can shape it to a narrow front pocket
- Five per box, funnel included for the one-time water fill

What owners say about this pack
★★★★★Flight attendant approved ice packs!
These ice packs are truly phenomenal. I’m a flight attendant so I’m always on the go with long hours and sometimes hotels without fridges. So far when I’ve used them they’re still frozen solid and ice cold after 12-15 hours of work, my food stays frozen!! The other day I had a hotel with a fridge but it didn’t quite get as cold as id like it to so I popped my food in the fridge with the ice packs and after a 12 hour day and 12 hours of being in the hotel fridge 3/5 of my ice packs are still frozen solid and cold! I don’t think I’d ever buy anything else. I hope they do come out with maybe some that are half the size of the small so I can put it in smaller places but highly recommend these for those working long days with no way to refrigerate!
★★★★★Super cold lasts a longtime
These are hands down the best ice packs and I've tried out about 30 types. I use these every day for migraines. They last for several days in a well made cooler like yeti or igloo. They last maybe 2 days with a couple of them in fabric coolers in the open they last several hours. I shaped them more into a roll shape to use behind my neck. I actually got frostbite last summer from one of them they are that cold. Of the 5 of them I bought several years ago, only one has finally leaked and that's years of everyday use
