Description

Engineered with a circular, angle-free bottom, the Hydra Cell resists abrasion and puncture damage, perfect for rugged pack use. It glides effortlessly into vest or belt pockets and conforms comfortably to your body as it empties. The high-flow silicone bite valve ensures rapid hydration with minimal effort, so you can stay focused on your stride.

Weighing only 44g, the flask’s soft body is compressible, flexible, and dishwasher-safe, making it ideal for long training days, race day efforts, or fastpacking adventures. Built from PU, PP, silicone, and POM materials, it's free from BPA, PVC, and phthalates, ensuring a safe, clean-tasting hydration experience every time.

Whether you're logging big miles or heading out for a quick trail loop, the Hydra Cell delivers hydration without bulk or fuss, helping you stay fuelled and moving with minimal disruption.

How does it work

The Instinct Hydra Cell works by combining high-quality, compressible materials with smart design features to offer performance-driven hydration. The large 46mm opening allows for easy filling, even with powders or ice, while the soft body collapses as you drink, minimising sloshing and bounce. The circular bottom prevents pressure points and increases puncture resistance, making it tough enough for technical terrain. The bite valve delivers a smooth, fast flow, so you stay hydrated without breaking pace.
