Hydro-3 has been designed specifically as an active riding pack with our unique Quadloc harness system. Providing a level of fit and comfort unequalled by any other hydration system. With a fully adjustable back-length and unrestricted underarm movement. Once set, the pack is exceptionally convenient to use, with none of the harness strap re-adjustment necessary on conventional harness systems. The adjustable back also allows the pack position to be moved up to allow large waistpacks to be also worn. Hydro 3 can be worn with or without a waiststrap - we recommend to use a waiststrap for maximum stability, when carrying the full 3 litre (100 oz) water capacity.

The pack is supplied pre-set to level 2. For XL fit move to level 3 and level 1 for XS fit.
Step 1: Firstly, push the harness strap back into the pack, to release the harness-web tension.
Step 2: Shorten or lengthen harness by moving slider on web (equal both sides).
Step 3: Pull harness strap back out of pack, to tension harness web.
Step 4: Put on pack and adjust fit as on a conventional harness. Do not over tighten - tidy loose ends - ends under elastic loops. Once set, the harness do not need to be re-adjusted each time as the pack ergonomics allow the harness to open wide for arm access.

Amazing bit of kit. High-sided on the road at 50mph, landed on my back and skidded down the road on my fully packed Hydro. The Hydro was left with just a few holes and snapped elastic. All my stuff in the Hydro was fine (including ipad) and the water bladder didn't burst. Highly recommended (the hydro not the crashing and skidding down the road bit!)

Been racing RedBull Romaniacs with this bag for 3 years.
Nothing ever broke, never moved from it's position on my back, never run out of water nor from tools. Never gave me any shorts of problems.
This bag is so good i never considered downgrades!
You'll be surprised to see how much it fits with the sacrifice of 1 lt of water.
I wish all products were of similar quality of production!
It's materials don't fade, don't rip, don't tear.
One of the best companions to hard enduro i've owned!

Love the hydra 3. 3 litre bladder instead of the usual 1.5 or 2 you get with other brands. Which is good because you can easily drink a litre an hour when doing enduro events and the 3 litres will see you through a 3 hour race. Water tube has a cap on it to stop it getting full of shit which I like when greenlaning. It can also be removed if you don't want to use it. Bite valve is nice and you get a good flow of water through it. Water tube can be used on either side. Quad lock harness is great because it distributes the weight over your chest and shoulders so feels like you have next to know weight on, reducing arm pump. Has one pocket on the front which is enough room to get your phone keys and a thin wallet in. I bought the the us 5 drybag as well for carrying KTM tool kit and some other bits, which once you've worked out how it straps on is excellent.

The usual high quality Kriega material. The only problem is how to fit the bladder - do you fill it first and then struggle to squeeze it into the pack or squeeze in first and then fill it up? Not a lot of room in the side pocket but it's not there anything big though. Used it on the moto and the mountain bike and it was comfortable for both. Give it time for the material and straps to flex a bit, a little stiff to begin with. More detail on how to fit the other bits to it would be nice (kube and US5 etc).

Great product as always from Kriega. Superbly put together. Only limited use so far as its early days but does what is says.

Very comfortable, holds more than enough water to keep me hydrated, the straps are well designed. Would recommend to anyone. Well worth the price.

Ace Fit-completely snug to the body without restricting movement which is vital in Hard Enduro. Bit disappointed I could not get my Kriega tool roll in the front pocket so this really is a light hydration pack for minimal tools, small first aid kit,mobile and wallet. Anything more and you'll need a larger pack. Perfect for my early morning sunrise ride!

I think that's about as good as it gets.
