For trailblazers and pathfinders: The original Ultralight insulated water bottle is the versatile all-rounder for those who like to forge their own paths in everyday life. Not too big, not too heavy: Ultralight fits easily into any bag thanks to its uncompromisingly compact dimensions and feather-light weight, making it always at hand when it truly matters.

Thanks to dishwasher-safe materials, cleaning is a breeze.
