UltrAspire introduces yet another milestone in hydration history! The Ultraflask 550 Hybrid Bottle has all the benefits of a softflask but with the conveniences of a hard bottle. The bottle is designed to sit as close to the body as possible to minimize movement when full. The soft-body shape helps with rapid access, comfort, and squeeze and the large cap opening easily fits ice cubes. So no more warm fluids on those hot summer days.
- Simple push/pull nozzle with high flow
- Soft and comfortable against the body
- Ultra squeezable with quick recharge
- Food-grade LDPE
*Hand-wash. Due to the nature of this ultra-squeezable bottle, it is not recommended for dishwasher use.
