Appears to be a decent product but expensive for what it is, missed out on five stars purely due to the price

Really good product. My last reservoir was cheap and has since died a death. So I went for an Osprey one with their all mighty guarantee, I have a few of their other products (rucksack and travel case) and I highly rate them and so far this is no different.

Osprey Hydraulics 2.5L

Brilliant in a word. Very well made as you would expect from a quality brand like Osprey. 2.5L just the right size for a days walking. Well worth the money, highly recommended.
