Learning from the limitations of other hydration systems, Osprey have created the Hydraulics™, a reservoir which has a lightweight handle to make filling and inserting easier and welded chevron baffles that provide stability and shape, combatting back panel bulges often encountered with flexible reservoirs. The bite valve has a simple turn on/off action and a strong magnetic system which keeps the hose and bite valve in place when not in use but offers hydration you when you need it.

Q&A (2)

Will this fit with the Osprey Talon 44l rucksack?

3rd Jun 2019, submitted by Eve

Hi Eve. Yes this hydration bladder will fit in the 44L hiking pack, this size of pack will normally hold a 2 or 3 litre hydration reservoir. Using a smaller one will add less weight and give you more storage space. Many Thanks.

Does this product fit together with product number 200341?

24th Apr 2019, submitted by Jack Preston

Hi Jack. With this being a travel bag and less focussed on quick paced movement it wont be compatible, not having the space to store this water tank in the back area as well.This would work more with the day pack and hiking range. I hope this helps.
