Built for the Vest. Designed for the Distance.

The Trekker Essentials Ultralight TPU Soft Flask is engineered specifically for runners, trail athletes, and hikers who use hydration vests, waist bags, or hydration packs. Available in 250ml, 500ml, and 750ml, each size is optimised to fit standard vest flask pockets — sitting flush, staying secure, and collapsing progressively as you drink.

Made from food-grade, BPA-free TPU, it's one of the lightest hydration options available for endurance athletes and backcountry adventurers.
