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.

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.

Fit for purpose, fully functional, no gimmicks or no non sense features, what you see is what you get, and what you get is what you need.
I ride extreme enduro at senior amateur level.
I can only recommend Hydro-3 as the logical evolution for anyone still using Camelbacks.

I use this pack when mountain biking and it is nothing short of superb. I've had mine for about 5 years now and it's still as robust as ever after many long and hard trial rides in north wales. I've tried friends camelbaks and all feel far inferior to my Kriega. Why? The harness is amazing, fits incredibly well with no wobble (even without the waist belt fastened). Sure there's not a lot of storage space, but the modular design means I can just strap on the 5litre extension pack if I need it.
The materials and the weatherproofing is also way above the competition in terms of build quality. Nothing else comes close.

This is so comfy it's like wearing the R15 - you totally forget you have it. I also like that you can use the reservoir in the R15 and R25 rucksacks I have if you do need the extra room. Great design.

It is the best hydration pack I have used. I have used a few packs including Hydrapak, Camelbak and Karrimor also. There are two stand out reasons that I can tell. 1- Shoulder straps/harness, it is a little bulky when you look at it, but the freedom of movement that you have in it is outstanding, and by far the best of any pack I have used. Also the adjustment range of the pack. 2 - COMFY the fact that it's a 3-litre pack with storage space. May seem to some as a bit of hindrance, but it is very hard to find a 3-litre small compact pack, without carrying external pockets and 10 litres of storage. I got asked if I was going parachuting by one of my riding buddies when I clipped up the front Quadloc harness, he said "that's the best idea I have seen for a pack, gets it out of the way of your armpits" He was impressed. Thanks again for the excellent service and bringing the product in.
