One of the most frustrating things about backcountry hydration is how difficult it is to clean and thoroughly dry bladders, bottles, and other water containers. The Cnoc Vecto collapsible water bottle solves that problem, and others, with great design. The soft, BPA-free bottle is easily filled, cleaned, and dried thanks to the bottom of the bottle featuring a slide-off-and-on closure system that allows you to easily scoop up water for filtration; reach in and thoroughly clean its nooks and crannies; and open it wide for adequate, mildew-free drying. The Vecto comes in 2 and 3 liter sizes, is super light, rolls up into a compact package, and is tough as nails. Fill a Vecto from home for day hikes or use it on longer treks with one of several water filtration systems they are compatible with, like a Sawyer,  Katadyn Befree, or other filters.
