Kriega Hydro 3 Hydration Backpack

The Hydro 3 has been designed specifically as an active riding pack with Kriega's 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 - Kriega recommends using the waiststrap for maximum stability, especially when carrying the full 3 liter (100 oz) water capacity.


  • 3-litre reservoir
  • 1-litre side access zip pocket
  • Removable waist strap
  • Unique QUADLOC harness: adjustable back length with total arm freedom
  • Side access pocket
  • Removable waist strap
  • SUPERSPACE: 5mm airspace back
  • YKK water-resistant zips

Great addition
I actually bought this product for use whilst adventuring on my mountain bike (The pedaling kind...). After reviewing various hydration packs, I settled upon this one for the following reasons: I'll begin by mentioning that I have owned a Kriega R25 for approximately 3 years and I absolutely love it. The greatest priority for me is comfort. I do a fair bit of distance riding on both the motorcycle and bicycle and anything that is not comfortable quickly contributes to fatigue. Kriega, in my opinion, has the most comfortable harness system of any pack that I have ever worn. Water capacity is certainly adequate for a day excursion. Quality on both the R25 and Hydro 3 has been very good. I've read this on other reviews and will concur that the the storage capacity (separate from the bladder compartment) is limited. Like every product intended for a purpose, the intent of this pack is clearly hydration which, in my opinion, is performed extremely well. Attention to detail such as the insulated supply tube (keeping the water cooler for that first sip), makes this pack a great choice. Regarding storage capacity, the integrated storage compartment is intended for "essential" items and is not designed for extra clothing, heavy tooling, or the spare filing cabinet that I typically need to carry for a weekend. If unable to secure items under the supplied elastic lash cord, the need for extra space is remedied by the addition of a US-5 or US-10 pack. This does come at a nominal fee, of course, and is the sole reason that I give the pack a slightly lower "bang for the buck" rating. Adding the US-5(10) does interfere with the elastic lash cord on the back of the pack so use discretion before adding either and establish what additional items will need to be carried. This brings me to my final point regarding my choice. Since I already own both an R25 pack and a US-5, this product is the perfect modular match for both my motorcycling and bicycling habits. I can use components (i.e. water bladder and US-5) on either pack with ease and efficiency. Whist the Hydro 3 may be considered a heavier option for mountain biking, the comfort more than compensates for it by reducing fatigue. On the motorcycle, I've got an engine to offer locomotion so, with superior comfort, weight is not even a factor. In all, it's a great product for which it is designed and has nifty features that other hydration packs do not offer.

Great hydration pack! I don't even know I'm wearing it. The pack straps fit nicely over my neck brace side wings and actually helps hold my neck brace down. I removed the waist strap. you don't even need it.

Super functional.

Amazing hydration pack / platform
Everyone has probably used a CamelBak at one point or another. This is exactly like that but with a couple tweaks to make it more motorcycle specific.

The adjustable strap system is great once it's adjusted. Adjusting it is straight forward, but can be a slight pain because you need to put your gear on, put the pack on, drop into a crouch, take it all off, and adjust again. Remember to adjust it when the pack is full of water. It expands and can be a little tight if it's adjusted when empty.

Pack capacity for water is huge. It matches CamelBak's 100oz highest capacity pack with comparable pricing. Fill up is easy with the included ziplock-style fold over top. Slide the clip off, dump water into it, fold and slide back over. No leaks in sight yet.

Once you add in the US-5 / US-10 expandable capacity and great harness, the pack will best any CamelBak or similar hydration system.

Water when you need it.....
I bought this for a 5 day off road class and this hydropak is really a tough product. It withstood multiple bike falls.... and held enough water for a day of riding(3L), especially in warm dry weather.

The adjustments are good and once the pak is adjusted for your fit this pak does not go anythwere. No bouncing, no side to side movement no sag. Weight distrubution is such that you don't know you are wearing 3L of water.

This pak does as advertised and then some. While it might seem pricey, it is worth everypenny after seeing some other pak sag and bounce around.

Great Hydration Backpack!
I got rid of all my other hydration backpacks that I had accumulated over the years once I got this one! The harness completely removes the weight from your shoulders, making carrying 3 liters of water on an all-day dirt ride Very Pleasant! I wish the side pocket were a little bigger, but I am going to add a US-10 pack so that I can pack extra gloves, more food, etc. I also have a Kriega R35 backpack, which has a similar harness, which a passenger wore on an extended tour of Washington, and she commented on how comfortable it was to wear, even when stuffed full with her clothes.

Buit to the 9's
First impression, it's really well built and adjusts easily. I wear this wile enduro racing in NJ/PA area and it works well. It's heavier then some on the market but I find the extra reinforced straps help keep it from swinging around. It also doesn't cut into my neck or shoulders like standard camalbacks have in the past. The bladder can be a little tricky to pull out but after you've done it a few times no issue. The directions provided with it aren't great nor is the website. I found just take sometime and play with the straps and you'll find the right fit. Over all it's well built.

I don't know if mine is defective, but it leaks from the bite valve a lot. Even when the valve is locked, it leaks a little bit. It soaks my crotch and legs over a couple hours of use.

If it didn't leak so badly, it would be great.

Military grade construction
Love the ruggedness of this hydration pack. can also be a useful hiking pack

1. Rugged construction / durable
2. Even weight distribution
3. Easy buckle

1. Price is on the premium side, but if you want to have a hydration pack that would last you a few years (at least), then i haven't come across a more suitable option
2. in case you are planning to carry any substantial load other than water, get a proper backpack

will definitely buy more kriega products going forward

I need a hydration pack for a weekend adventure ride. The size was just right, easy to fill and I never felt it on my back all day. I did remove the waist belt as the video recommended. The outer pocket was large enough to stash a few cliff bars and powerade mix packets. I am extremely happy with it.

I love this hydration pack! It's amazing how much water it can hold. Even when it's full of ice and water I can barely feel it on my back. It's great to be able to have a drink while I'm riding and not have to stop to do it. Fill it with ice and water in the morning and it's still cold at the end of a long day of riding!

I have the US-5. On Kriega's website it show them using tie down straps that my US-5 didnt come with to mount it to the Hydro pack. Do you need to buy the straps separate or can you make it work with the provided straps that come with the US-5?
James G on Jun 5, 2016
I'm looking to by some Kriega bags for 8-day trip and I wanted to include a Hydration system. carrying all this bulk and wait on my back seems not ideal. Has anybody seen a system where the hydration back in on a tack bag instead? I have the Kriega tank adapter and thinking adding a Platytus big zip bag inside the US5 or US10 there instead (probably better quality plastics/less taste and chemical exposure). Am I missing something fundamentally flawed about having the hose coming from the tank bag? (this is for road use on standard and dual/sport bikes)

Is the Hydration bladder compatible with their R25 backpack as well?
A shopper on Jan 25, 2014
BEST ANSWER: Yes, the bladder from the Hydro 3 is 100% compatible with the R25. The exact location of the hydration bladder depends on which R25 you have. From the Kriega website: "When installing in a pre-May 2013 Kriega R25 motorcycle backpack, the reservoir fits in the outer pocket with the drinking tube being routed out of the top of the zip and over the shoulder. On the current R25, the tube has a dedicated, covered duct in the top center of the main compartment that the tube can be fed through."
Can this be worn while wearing a neck brace. I.e. Leatt ?
Chris W on Jan 13, 2016
BEST ANSWER: I don't use a neck brace myself - however I've used the backpack almost every ride. I ride about 200 days a year so I think I can give you a good answer.

The shoulder straps are far enough from your neck that I believe wearing it with a neck brace will be no problem.

As far as the weight of the backpack - even with 3 liters of water in it - honestly you don't know you are wearing it.

I hope this helps you.

Does this pack come with the 3 liter hydrapack?
Colin H on Oct 24, 2016
BEST ANSWER: Yes, it comes with the 3 liter hydrapack with the insulated tube.
I understand there is Limited storage, but will this fit a Kriega Stash Wallet?
Ben J on Jun 15, 2017
BEST ANSWER: There's actually a decent amount of storage. I put my wallet, iPhone, keys, pack saw and snacks for the day. All with 3L of water. Highly recommended the hands free kit!
How do I get rid of the awful plastic chemical taste coming from the bladder?
Adriano J on Dec 22, 2014
BEST ANSWER: the plastic taste left after 2 to 3 use for me.
or you can try to put another liquid than water inside, like ice tea.
Can it be worn with LEATT chest protector ?
A shopper on Apr 16, 2014
BEST ANSWER: Yes, I wear mine with a Leatt pro lite chest protector and they fit together great. The harness on this hydration pack really keeps it centered.
