Testing Period

Tested By

We evaluated the Fit & Fresh Cool Coolers alongside 8 competitors in a controlled lab and real-world settings. Freeze and thaw testing: Packs were frozen at 0°F for timed cycles (measured via thermocouple probes), then placed in a 75°F ambient environment to track phase-change duration—aiming for 80% ice retention after 8 hours.

Cooler performance: Loaded into popular lunch boxes (Bentgo, L.L.Bean, Yumbox) and soft coolers (Igloo 6-can) with 40°F-start sandwiches, dairy, and fruit; internal temps monitored hourly for 12 hours using data loggers. Fit was assessed in 15 container types, from kids' minis to adult totes.

Durability trials: 50 freeze-thaw cycles, 10x 3-foot drop tests on concrete, and leak checks post-puncture simulation. Customer pain points like packaging were replicated from 1,000+ Amazon reviews.
