The 'First Wave' (military spec.) reservoirs are designed for extreme environments. The 0.4mm thick Thermo Polyurethane (TPU) is twice the thickness of the standard consumer model. Fully reversible for easy cleaning / drying. A Wide Slide-Seal™ top makes it easy to fill and creates a leak-proof seal. The Hydrofusion™ tube is durable and lightweight with built-in foam insulation, this simple, but breakthrough tube helps keep your water cooler in even the hottest temps.

Surge™ Bite Valve naturally ergonomic design with twist on/off function and protective cover. 

Plug-N-Play™ connect system lets you easily disconnect the drink tube (an auto shutoff valve prevents leaking) and remove the reservoir from your pack for convenient refilling while leaving the drink tube in position.

7th Apr 2016 if you need hydro.. Kriega one is the only option. Perfectly compatible with all backpacks, easy to install, durable and very detailed quality.. I have a plenty of stuff from this UK company for many years now and everything is still in a ming condition, even when its sometimes hardly abused ;))))

12th May 2015 Hydrapak Great addition to my R20 rucksack for France touring this year. good quality bladder, easy to fill and the dry break tube connector means you can pull the bladder out without disturbing the rest. Nice and wide fill point for cleaning etc.

8th May 2015 Best design I love the design of this hydrapak - it's so much easier to access and clean than other products out on the market

21st Apr 2015 Awesome bit of kit Easy to install, easy to use, easy to clean. Loads of excellent little details that make it worth the cost. Doesn't leak, no matter what you do to it (within reason, of course) & the dry break for refilling, without tube removal, is just so easy. Well done Kriega, another great product.

26th Feb 2015 Too big for R15 I really like the filling and sealing method of the reservoir. Also the way the tube attaches is excellent. However I do feel it's slightly too long for the R15 backpack.

19th Jan 2015 A* products Kriega products are in my opinion, far above any of their competitors. I sold my Ogio Mach 5 backpack and replaced it with the R20 to take as a daypack as I travel south east Asia on motorbikes. I therefore bought this water reservoir and again world class manufacturing! With Kriega you get practicality with the piece of mind that products will not break and will last for years. Keep doing what you're doing.

30th Sep 2014 Great upgrade to standard hydrapak I bought this as a reservoir for a Dakine Ski/Snowboard bag which uses the standard Hydrapak unit. The Kriega one is much tougher, thicker material and the tube is permanently insulated. Fits the bag perfectly and was cheaper than the original version. Great product.

29th Sep 2013 Relatively expensive, but desirable The reservoir arrived promptly and appears to be well made. It fits happily, if not snugly into my R15 and the hydration pipe is the perfect length. I personally feel that the pack is quite an investment when I have already bought the R15, but Kriega products are probably made in small volumes and there is no question that their products are well designed and will be durable for the longer term

5th Feb 2013 Easy to Clean! Super easy to clean unlike other hydration packs.

7th Oct 2012 Sturdy product Bought the 3 litre reservoir to fit in my R15. Maybe it would fit a little bit better if it was 1-2cm shorter, a bit wider and a bit thinner (if possible). Not saying that it does not fit in the R15, only that it could be better. Have only used it on 2 trips until now, but the water gets a bit of a rubbery taste, hopefully this will go away with time. Otherwise the product is bomb prof and the hook & loop tube-attachment combined with the isolated tube is brilliant. I have not regretted buying this product.

26th Sep 2012 Another great product! Bought the 3L Reservoir to fit into my R20 rucksack. Been meaning to do it for ages but an off roading weekend made me take the plunge. Glad I did. Fits perfect, works a treat and the same top quality you expect now from Kriega. Fell off 4 times and bag and reservoir were fine. Also detaches from the tube/valve for easy emptying and filling up. Well done Kriega on an other quality product.

27th May 2012 Great bit of Kit I can't sing the praises of this product enough as well as all the other Kriega gear I have. Top quality material & fits in my R15 rucksack like a glove. Their customer service is second to none.
