The all-around adventurer's choice, Hydro Flask's 32oz Wide Mouth Water Bottle always seems to be part of the kit whether you're ski touring, hiking, or simply heading to work. Its TempShield insulation keeps water ice-cold for up to twenty four hours, and it also keeps hot drinks nice and toasty for up to six hours. Hydro Flask updated this years' model with a flexible loop on the wide mouth cap for long-lasting convenience.
