OMM says

OMM flasks are flexible and compress down in volume as you drink. Eliminating water sloshing/bouncing inside and reduces the sucking effort. The durable thermoplastic allows for easy storage on the move. Also features a secure bite valve to ensure no spills when stored.

Our Verdict

The Ultra Flexi Flask is a durable and flexible flask with a soft feel bite valve. Unlike other flasks its deigned to compress as you drink to prevent the bouncing of fluids. It has a wide neck opening which allows you to insert powders and gels in as well as water. The durable outer has good grip which will help you to squeeze out all the gel or liquids. And once you’ve consumed the contents it can be easily packed away in to a pocket. It’s deigned to fit into the small stash pockets on OMM packs but would also be able to fit into other branded packs.
