With all the benefits of a soft flask without the usual problems such as taste and staining from carbohydrate drinks, the UltrAspire UltraFlask 550 is a great feeling, easy-stowing hybrid between a hard bottle and a soft flask. Made from LDPE, this on-the-go flask uses a push-pull nozzle for accessible hydration, quick recharge, and easy cleaning.
