If you only buy one set from us, this tends to be it — four square packs, 10" x 10", with more owner reviews than anything else we make. The square shape is the reason: it fits the floor of a 16 quart cooler, stands against the wall of a 48 quart, and folds into an insulated backpack for a twelve-hour shift. One pack in the cool months, two in July, and lunch and drinks stay properly cold from the first coffee to the drive home.

Why this pack
  • Square 10" x 10" x 1" packs that fit almost any cooler wall or floor
  • Four in the box — split them between a cooler and a lunch backpack
  • Funnel and caps included; the water goes in once and stays
  • Frozen at 18°F, so a pack placed under meat keeps it near-frozen

What owners say about this pack

★★★★★The best ice packs ever!

These are the best ice packs I’ve had! They really do last 8+ hours in a cooler and keep drinks and food cold. I got the medium sized ones and it’s pretty darn perfect for the cooler I have. Maybe a little smaller would have been nice but not a big problem in my opinion. Great value for the money!
