Pure Outdoor by Monoprice Emperor Cooler: 25-liter $80, 50-liter $120, 80-liter $160

Any Conditions: The coolers are ideal for even the hottest and coldest conditions your adventures might find. Keep cold items cold for more than 130 hours or hot items hot for more than 150 hours, regardless of weather conditions.

Securely Sealed: Ordinary coolers are a magnet for bears, who open them easily and either consume or make a mess of your food. That is not the case with Emperor Coolers. The durable rubber anchor latches are augmented with steel reinforced padlock holes at both front corners. Unless the bear can pick a lock, your food is safe and secure!

Stay Tied Down: Tie-down slots on each side allow you to use with tie-down straps to keep your cooler from sliding around in the back of your truck or boat.
