The Hydration Reservoir 1L is the perfect partner for your Strive running backpack. It fits the Strive series and has a slim, vertical design.

The reservoir features Hydrapak IsoBound™ insulation technology that will keep your water cold and give you a more comfortable carrying experience, even in warm temperatures. It is engineered to keep fluids at an ideal temperature 38% longer than a standard hydration reservoir. After all, cold water is more refreshing and will keep you going for even longer sessions.

The reservoir is made of ultra-durable, abrasion resistant TPU with RF welded seams for superior durability and elasticity. The bite valve self-seals after each sip and features a smooth twist on/off bar to prevent leaks when not in use, and the Hydrapak Slide-Seal™ top opens wide for quick filling and closes tight for a leakproof seal, includes tether to prevent miss-placing.

This 1 liter bladder is custom made for Silva and it fits all models in the Strive-series. Simply thread the hose through the smart outlets in order to have your fluids easily accessible at all times. The V in the product name stands for vertical, meaning that the bladder should be placed vertically for optimal flow.
