Compact, leakproof hydration bladder with easy-fill wide opening for hassle-free hydration on the go. Fits all Compressport trailpacks.

• Hydration line-up would not be complete without the Compressport Hydration Bag. This convenient water bladder boasts a generous 1.5L capacity, making it the perfect companion for all-day trail runs and outdoor adventures. Fitted with a flexible hose and intuitive fast-flow bite valve, your hydration just got a lot closer, faster and easier.
• Featuring a full-width opening at one end, the bladder can be turned inside-out for easy scrubbing. All elements can be taken apart if it requires a little more thorough cleaning at any time. Just like Ergoflasks, this flexible container is built to last with 100 % PVC and BPA-free materials so you can safely use, clean and use again. The Hydration Bag is perfectly compatible with Ultrun S Pack Evo 15 but also fits handily into other trail packs, providing unbeatable performance and functionality on the go.
• So whether you're hitting the trails, climbing mountains or simply exploring the great outdoors, the Hydration Bag ensures you stay hydrated and fuelled for the journey ahead. Good to know: this hydration reservoir comfortably meets the UTMB 1-liter mandatory fluid requirement.
