Yeti have created the Yeti Hopper, an ideal solution for short trips, instead of running around with a giant cooler in the fierce heat, you can just throw this shoulder bag on your back, or sling it into a canoe. The soft-sided cooler has a 5.2 gallon capacity and is sealed with a waterproof drysuit zipper. The inside insulation cell is thick enough to keep the ice solid for several days.
