UltraFlask 550mL

UltrAspire introduces yet another milestone in hydration history! All the benefits of the sport bottle without the downsides and all the benefits of a soft flask without the usual problems such as taste and staining from carbohydrate drinks. This great feeling, easy stowing bottle is a hybrid between a hard bottle and a soft flask! The light weight super squeezable UltraFlaskTM stands alone, is fillable and easy to clean, has high flow and fast recharge, is soft, flat and stable against the body, is easily accessed and returned to a vest pocket even when empty, and its great for waist packs too!
