UltrAspire introduces another milestone in hydration history! The UltraFlask 550 Hybrid Bottle is a cross between a hard bottle and a soft flask. The high flow push/pull valve is easy to use and makes it perfect on the go. The lightweight super-squeezable UltraFlask stands alone, and it is fillable and easy to clean. It allows high flow and fast recharge, and it is soft, flat and remains stable against the body. It is easily accessed and returned to a vest pocket, even when empty, and great for waist packs, too! The UltraFlask 550 Hybrid Bottle is BPA-free and made in the USA.
