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.

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.

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.

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.

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.

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.

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.

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

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.

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.
