I bought the classic model for my husband &amp; we gave it a test run last week. We did an all day jeep topless ride and this cooler was a winner. Held up in all day 95 degree weather (in the sun) and we still had ice at the end of the day. Perfect little gem to tote around while on the go. As long as it stays upright / or tightly sealed, no water seeping anywhere - most difficult in southern humidity.
