Shrinks When Empty. Performs When Full.
The Trekker Essentials TPU Collapsible Soft Flask is built for athletes and adventurers who refuse to carry dead weight. Whether you're mid-race in a hydration vest, scrambling up a trail, or cycling through mountain passes, this foldable flask delivers water on demand — then collapses flat when you're done.
Available in 250ml and 500ml, with soft nozzle and straw variants. Weighing just 30–75g depending on size and style, it's one of the lightest hydration options you'll find.
