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, when carrying the full 3 litre (100 oz) water capacity.

Kriega Hydro 3 Hydration Backpack 4.7 5 11 11
First Class 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. March 23, 2015
Top Quality Product Comfortable and just the right size. The quality of all Kriega products is excellent. I have four. December 22, 2014
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. October 2, 2014
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. August 21, 2014
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.

Perfect on very hot day Wide mouth allows you to put in ice with water. Great on 90 degree plus days. Rides well at high speeds. July 21, 2014
Very comfortable hydro pack Great overall hydro pack that is great for what it was designed for. Easy to wear and you never feel any pressure in your shoulders or back like you do wearing other hydro packs. The quality is first class and the pack is very well made. The negatives are: Little on the high price for a hydro pack. Only comes in black. limited to motorcycle use only do to the heavy duty shoulder strap system. The pocket in front of the bag is very small. July 7, 2014
Really excellent versatile and well made hydration pack. I'm fairly new to Kriega stuff and between this pack and my new R8 waist pack, I can say I am wholly impressed with their design, construction, quality and value. This hydration pack is well made, thoughtfully designed, carries the load evenly and securely. The included bladder is feature laden and compared to your average Camelbak bladder (which I previously was using). The wide full-width opening with folding closure makes filling, cleaning and drying easy, the Velcro tube attachment is handy and the insulated tubing is appreciated for keeping that first gulp of water cold. I have no reservation in recommending this pack so long as you are looking for a simple straightforward, lightweight, low-profile hydration pack. If you need carrying capacity I hear it can be easily paired with their US 5 or 10L packs. October 22, 2013

A shopper asked: Is the Hydration bladder compatible with their R25 backpack as well? Jan 25, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Jason K: 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." Jan 25, 2014

Rhett V: The r25 backpack does have a space for the hydration bladder which can be purchased separately. I have this hydro 3 backpack for trail riding and use an r20 for commuting. When I go on a long ride I just swap the bladder into my r20 so I have hydration as well. You could do the same with the r25. Jan 25, 2014

Daniel H: Mostly. I use it in mine throughout the summer. It fits in the back, side-opening pocket just fine. The only issue is the hose could be a few inches longer to work better. It works, but would be a lot better if the hose were longer. It gets better as the bladder empties too. Jan 26, 2014
Reply to Daniel Good answer? Yes (0) No (0)
MICHAEL M: The Kriega website says that the hydration bladder will work with the R25 backpack. Navigate to here: http://www.kriega.us/r25-motorcycle-backpack/

and pick "pack layout." The description on the left will confirm this.

Eric C: No, it has its own harness. The bladder is very nice, 3 liter, and can be used in the R25. I guess you could strap it on to the outside of the R25 or R30. The quality and design is the best. Jan 25, 2014
