All Hydro Flask products are made with 18/8 pro-grade stainless steel, and designed to be the lightest weight and slimmest profile insulated bottles on the market.  They will keep your beverage of choice ice cold for 24 hours or piping hot for 6 hours, and you get no condensation on the outside of your bottle.

This wide-mouth bottle has a Flex Cap with an internal honeycomb insulation and flexible strap.  The bottle will fit most backcountry water filters and carries enough liquid to last most of the day.
