The designers at UltrAspire have logged enough trail miles to know how important it is to stay fueled. The Formula 250 bottle is a unique tool for doing just that, offering 250 ml of capacity and a high-flow cap for gel intake.
The soft-sided but durable flask weighs just 2.0 ounces and has a wide opening for easy fill-ups and cleaning. The threaded cap has a convenient flip lid with a broader opening than standard drinking bottles to keep fueling up from being an impossible task. The ergonomic shaping of the bottle allows it to stow conveniently in most running pack pockets and the flexible structure allows it to roll-up when empty for convenient space saving. The flask’s silicone material is durable, stain-resistant, and taste and order free. It is dishwasher safe and an integrated bottom loop allows you to hang the flask upside down for drying or for lashing it to your pack.
