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. – Reviewed by Ultralight Outdoor Gear Features Durable Thermoplastic Polyurethane (TPU) construction with extra grip Flexible / squeezable, lets you easily squeeze out gels or liquids Compresses as you drink reduces sloshing/bouncing of fluids Slim and lightweight, easy to fill and clean with wide opening Interchangeable straw & bite valve BPA, PVC and Phthalate free, will not taint taste Specifications Weight 38g Volume 350ml inc straw Dimensions 23 / 5.5 / 3.5cm Fabric TPU (Thermoplastic Polyurethane) Help and advice: What does BPA Free Mean?
