Its double-wall body and urethane insulation support extended ice retention, while the two available capacities suit different transport and storage requirements.

Key features
▸ Reinforced insulation in the body and lid
▸ Ice retention for up to 5 days, depending on operating conditions
▸ Heavy-duty polyethylene construction
▸ Two flexible latches that can be opened with one hand

How it works and what it is for
The cooler works with ice or freezer packs placed around items that have already been chilled. Its insulation slows heat transfer and helps maintain a low internal temperature during travel, picnics, camping, fishing and other outdoor activities. It does not actively produce cold and requires no cable or battery.
