Osprey Hydraform 3L Reservoir System

Rated 4.8 out of 5 by 6 reviewers.
Rated 4 out of 5 by Good, but... Needed a new bladder for my raptor when the last one split after an over the bars incident. This new one quite different. Different materials are used and it seems bigger than the original one. Doesn't flavour the water which is good, but the cap is fiddlier than the first one. Overall a good product but expensive for what they are. 17 August 2015
Rated 5 out of 5 by The Best Hydration System Every aspect of the design for this has been well-researched and executed to a tee! From the easy to fill and seal cap, to the brilliant magnetic mouthpiece holder and comfortable drinking valve. I went for the larger size (what will hold a lot will hold a little!). Two pieces of advice for people new to hydration bladders: 1. Take spare water in a bottle, as you don't know how much water you have left in the bladder unless it's full.... or empty - then it's too late! 2. Once cleaned out, store the bladder in your freezer to keep bugs away with no nasty chemicals. 06 July 2015
Rated 5 out of 5 by It's a water bladder, it works very well with Osprey packs As an owner of several Osprey packs I thought I'd give the hydration bladder a try. My first experience of these things was a number of years ago with CamelBack and mountain bikes. Seems the tech has moved along somewhat! The bladder is easily filled, the rigid spine makes for east insertion into pack, the left or right pipe easy to fit and the magnetic sternum strap anchor works a treat. As does the bite valve,mdoesn't leak, gives you good flow to get a good drink without unnecessary sucking. You can sivewel it 90 degrees to shut off if you need to. I also found it was ok to use the bladder as a water source at camp (out of pack), simply hold upright, squeeze against your body and operate the bite valve with your fingers to fill kettle / mug or pan. 27 October 2014
Rated 5 out of 5 by good item i have read a few reviews that suggest this item leaks, i have not had anything bad to say. Its good value not great but i dont wish i had spent less. its solid front handle and back plate stop it from sinking down the bag when its half full, and works pretty well keeping the bladder cooler than abient (the water in the hose is hotter than the fresh bag water). i am not a fan of bite taps on water hoses but this one works well and i have not tried to change it so must be good. its a shame the nice peeps at osprey changed the hose size so now my old osprey (not sure the name buts its grey) hose doesnt fit but not a big deal. so all in all i am impressed its really good not perfect by any means but then nothing in this world is you get a good value for money bladder that holds 3L and is a pleasure to use. what more do you want, ps i have not crashed my bike yet (my main use is while cycling) so i dont knopw how it stands up to impacts but thats by the by 21 July 2014

Rated 5 out of 5 Excellent for my recent mountain trip, and cycling too! As I already had a smaller hiking rucksack alongside my 90L sack I didn't want to spend out on a purpose built all in one. This did just the job, it fitted well into the back of my pack and was excellent whilst climbing Mt Toubkal in Morocco. It was easy to fill and clean, especially with the built in handle which runs the length of the product, and was very durable - no worries about it breaking or leaking! The magnetic clip which clips onto the strap of your bag is great too as the pipe is always easily accessible even in the most extreme conditions! Overall, and fantastic product that I would most definitely recommend!! 5 stars! 26 August 2013
