UltrAspire introduces yet another milestone in hydration history: This great feeling, easy stowing 550 mL bottle is a hybrid between a hard bottle and a soft flask! The lightweight super-squeezable UltraFlask™ stands up on its own, is fillable and easy to clean, and has high flow and fast recharge. It is soft, flat and stable against the body and is easily accessed and returned to a vest pocket or a waistpack even when it's empty. The UltraFlask 550 Hybrid Bottle is BPA free. Unlike some soft bottles, it doesn't affect taste and it won't stain.
Compatible with the Momentum 2.0 (which doesn't come with bottles).
- Simple push/pull nozzle with high flow.
- Holds 550 mL or 18 fl. oz. of liquid refreshment

Hand-wash. Due to the nature of this ultra-squeezable bottle, it is not recommended for dishwasher use.
