We love collapsible bottles – space efficient and lightweight. Our friends at Hydrapak have taken them to the next level with their SoftFlask collapsible sports bottle. With an award-winning design, these bottles collapse into themselves as you drink the water, eliminating water sloshing around. There’s no chance of this bottle leaking with their special on/off valve, on top of a non-leaking bite valve with dust cover. A handy finger loop attachment which can be completely removed if not needed and a wide screw cap are other great features of these bottles. Comes in five sizes – 150ml, 250ml, 350ml, 500ml and 750ml and 3 colors (orange, smoke/gray, white/blue). A stellar bottle for runners, hikers, travelers, or anyone!
