Hydration Bladder — Insulated Water Reservoir

An insulated water bladder in 1L or 2L with a wide-mouth cap and a drink tube, for any daypack with a hydration sleeve, such as our 18L Hydration Backpack. Free shipping.

An insulated hydration bladder for the pack's dedicated sleeve — or any hydration-compatible bag. Keeps water cooler for longer on hot trail days and routes through a drink tube so you can sip without breaking stride.

Built for the trail

• Insulated construction — keeps water cooler for longer on hot days.
• Leak-resistant seal — a wide-mouth cap for easy filling and cleaning.
• Flexible drink tube — routes through any hydration-ready pack's dedicated port.
• Food-grade material — safe for daily use, easy to rinse out.

When to reach for it

Pairs with our Hydration Trail Pack — 18L or any other hydration-compatible backpack. Choose 1L for shorter outings or 2L for longer days and hot weather.

Care

Rinse after every use, air dry fully with the cap off between uses, and avoid direct sunlight in storage.

Questions

Why is my hydration bladder leaking? Most leaks come from the cap or the tube joint. Wipe the cap threads, set the cap on straight and turn it until it is snug, and push the tube fully onto its connector.

How do I check it before my first hike? Fill it with water, close the cap and squeeze it firmly over a sink. Check the cap, the seams and the tube joint for drips before it goes in your pack.

Will it fit my backpack? It fits packs with a hydration sleeve and a tube port. The 1L bladder is about 30 x 17 cm (11.8 x 6.7 in) and the tube is about 100 cm (39 in) long.

How do I clean it? Rinse it after every hike and let it air dry fully with the cap off.
