Guides
Practical cooler buying content — ice retention explained, capacity sizing, rotomolded vs standard construction, and bear-resistance certification.
Why this page exists
Cooler advertising focuses heavily on "X days of ice retention" figures tested under ideal lab conditions. Real-world ice life depends on pre-chilling, ice-to-contents ratio, ambient temperature, and how often you open the lid — none of which are controlled in most marketing tests.
This page explains what actually drives retention, how to match capacity to your group size, and what the rotomolded premium actually buys you.

Hard cooler
Injection-molded or blow-molded hard shell; mid-range retention; lighter and less expensive than rotomolded. Good option when multi-day extreme retention isn't needed.
