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. The large cap opening easily fits ice cubes and is covered by a high flow push/pull valve. Made in the USA.
The light weight 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! The Ultraflask 550 Hybrid Bottle is BPA free.
