Just like their bottles, Hydro Flask’s new waterproof, soft-sided coolers are serious about keeping things icy cold for a remarkably long time. The Unbound Series™ Cooler Pack is light and comfortable to wear hiking up a trail or down to the perfect spot for an outdoor concert. Load up with plenty of room for 24 cans or whatever you're bringing along – and keep it all cold for over 48 hours. Dry storage pockets keep dry things dry, and side pockets give you a nice place to stash keys, phone, water bottle, or other essentials.
