OMM Ultra Flexi Flask with Straw 350ml

Jump to: Our Verdict / Features / Specifications

The Ultra Flexi 350ml Flask with straw is a compact and lightweight water bottle with an easy access straw for trail running.

OMM says

OMM flasks are flexible and compress down in volume as you drink. Eliminating water sloshing/bouncing inside and reduces the sucking effort.

Our Verdict

This Ultra flexi Flask is a soft bottle with a straw for fitting into running vest/rucksack pockets. Included in the package is an angled mouthpiece for ease of use on the end of a straw that can be cut to length to fit your exact requirements. The flask has a wide neck for fast and efficient filling, includes fill levels on the side of the bottle and the mouthpiece is an easy to use bite valve. Because the bottle is soft, as you drink the bottle compresses stopping the liquid from sloshing or bouncing around as you move.
