Hopper® M12 and M20 FAQs

No. However, the internal corners are rounded for easy cleaning.

No, but Hopper® Cool Bags have been durability tested, and the shoulder straps will comfortably carry loaded contents.

For best thermal performance we recommend a 2:1 ice-to-content ratio.

TPU is thermoplastic polyurethane and it does not contain per- and polyfluoroalkyl substances (PFAS).

Nope. The straps are sewn into the Backpack Cooler and are not removable.

The Hopper® M12 can fit up to 20 standard 12 oz cans, and the Hopper® M20 up to 36 (cans only, no ice).

The Hopper® M12 can fit up to 5 bottles of wine, and the Hopper® M20 up to 7. They’re also tall enough to fit them standing upright.
