When Yeti Coolers introduced its soft-sided Hopper 30 last year, the marine media knew it was just a matter of time before the company offered smaller sizes. The new Hopper 20 features a 4.6-gallon capacity and is made from 840-denier DryHide fabric, similar to the material used to make white-water rafts. The sturdy bag also comes with Yeti's waterproof zipper, borrowed from survival suits and hazmat gear. Yeti packed the cooler's sides with one inch of insulation and padded the EVA-foam bottom with 1½ inches. The 20 costs $299.99.
