UltrAspire introduces yet another milestone in hydration history! All the benefits of the sports 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 lightweight super-squeezable UltraFlask*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!
Hand-wash. Due to the nature of this ultra-squeezable bottle, it is not recommended for dishwasher use.

Very good lightweight bottle that fits nicely into the front pocket of Ultraspire running packs.
