Cooler Shock Screw-Top Ice Packs with Handle, Large 15.8" x 11", 3 Pack

This is the biggest pouch we make — 15.8" x 11", with the same lift handle as the medium. It lays flat across the floor of a tall cooler and turns the whole bottom into a cold plate. Surf fishermen tuck one on each side of a fish bag; tailgaters lay two under the drinks and one across the top of the food. It is the pack for when the cooler is big and the day is long.

Why this pack
  • 15.8" x 11" x 1" — sized for tall and 60 qt-plus coolers
  • Handle slot for lifting out of a deep, full cooler
  • Lays flat to form a cold floor under drinks or fish
  • Sturdy pouch that wipes off and goes straight back in the freezer

Use these in my fish bag I use for surf fishing and they work great on the Whiting I’m catching , I’ve had 8 fish in the bag in between two of these

★★★★★Good for Large Coolers

Great for large coolers, and freeze quickly. I do wish they would stay frozen longer though.
