One of the best hydration bladders on the market. The best features about this bladder design, is that it is the easiest to fill and clean. I have a bunch of Camel-bak bladders, all of which are no longer in use. The Camel-bak bladders have a big and bulky cap that can be difficult to remove and install. The design of the Klim bladder has given me no hassles. The Camel-bak design is more difficult to clean. Camel-bak sells a big "bottle brush" to get inside and scrub out the bladder. The Klim can easily be turned inside-out and thoroughly washed. October 16, 2014
Nice pack, but not for Badlands Pro Jacket I bought this pack to go in my Badlands Pro Jacket. Filled it up and loaded it up, it was so uncomfortable i did not use it. It would most likely be okay with 1.5 liters or less. I will just use it as a back-up. June 26, 2014
A good place to keep your water. I had the pack from a Leatt H2 hydration system, but the bladder and hose were gone. This Klim unit slipped in and worked perfectly. The material is rubbery and tough and resists punctures. The bladder itself is really easy to clean, because of the wide mouth opening at the top. Most bladders have to be cleaned with chemicals or fiddly brushes, but this one eliminates that worry. If you're the kind of person who "accidentally" forgets to empty and dry your bladder after using it, I'd recommend getting this one. The valve is good, but not great. I've only used it twice, but I'm starting to get the hang of it. Once you figure out how to hold it between your teeth, it's easy to get good water flow. October 28, 2013
Pretty OK, but too large for a Badlands Pro Well, it fits alright, but you'll only be comfy with about 1.5L on it. If you fill it with the 3Ls, you won't have enough room in the Badlands to breathe Very sturdy and easy to clean (this is very important in these products, you don't want stuff growing in there)l May 24, 2013
Excellent Reservoir and Mouthpiece/Valve I am very happy with the quality and price I paid for the Klim reservoir. As others have commented, I appreciate the angle of the mouthpiece which allows it to nicely fit into/under helmet. January 16, 2013
Love it! I bought this to replace my aging Platypus Hoser. I've been using it for a few years and it's starting to get funky... I wish I would have found the Klim sooner! Being able to flip it inside out to clean/dry it is great, but the bite valve is the real game changer. I don't know why all hydration valves aren't made with like this. The Platypus (and my wife's CamelBak) has a big 90 degree valve that makes taking a sip with a full-face helmet make me look like a cat trying to lick the side of its face. The slight bend in the Klim makes it sooooo easy to get it inside my helmet, and the 360 degree bite is great, too. Well worth the money!! August 27, 2012
Great product Exactly what I wanted for long rides through the desert! Easy to fill and clean, no leaks, and the valve is great. July 30, 2012
1,000 Miles Without Water Once, on a trip back from Raton New Mexico, I tried to make it all the way back to Redding CA in one day. I left Raton at around 7AM and was crossing the Mohave Desert by 10PM. There was a heat wave going on and it had cooled down to about 105 degrees by Midnight. Sometime at around 2AM, over the Tehachapi Mountain pass, I started to hallucinate. I was being passed by semi-trucks, who seemed to be traveling very fast and then I noticed my handlebars stretching and my tank elongating and I was thinking how weird and interesting that my bike was stretching like that. I looked at the speedo and found I was only going 25mph hour which was also odd to me. And then it struck me that something was very wrong. I drove on to the next exit which was one of the longest 10 minutes of my life and pulled off. It took me a long time to figure out how to shutdown the bike and get off it without dropping it. I was having very paranoid thoughts and I was having both aural and visual hallucinations that included, among others, lions in the grass, homeless undead people, and a gang member drive by. I was traveling with a hand gun and I went for it at one point but had poor motor control and dropped all the rounds before I could get them in my .38 snub nose. Being completely messed up in the mind, it took me a very long time to figure out what was happening. I knew I was hallucinating, and knew I was having a crisis, but I was too disoriented to think clearly. After some time, I realized that it had been a long time since I drank water. In fact, the last time I’d had anything to drink except Red Bull was back in New Mexico in the morning. I started to think that driving in full gear for 1000 miles without water, during a heat wave was somehow related to the homeless undead people coming up from behind me at that very moment. I pulled out a small bottle of water I found in my bags and drank all 12 oz. After a while, I started to come around a bit. I told myself, that as soon as I stopped hallucinating, I would get on the bike and find a hotel room. I was on the road sometime later and heading for Bakersfield. I checked into a hotel room at around 4:30AM, but I was still having mental problems. I called my wife and then tried to sleep but it was hard because of the 8 cans of Red Bull. I tried to re-hydrate myself with water. At around 8AM, I started to get very afraid of the people in the room next to me because they were very angry at me for making noise so late. This wasn’t actually happening, but it felt so real. I became so agitated with this thought that I trotted out of the hotel and started the last 450 miles home to Redding CA. The temps rose to over 115 degrees that day. I had a Red Bull and bought a couple bottles of water. I drank one bottle and used the 2nd one to wet my shirt. Didn't work. I made it as far as Patterson before I had a total melt down. I had to call the paramedics because I was so hot, dehydrated and messed up and I was fairly certain I was going to die. The paramedics explained to me that I was unable to hydrate because I hadn’t eaten anything and I needed the salts and electrolytes in the food to help me re-hydrate. They said that if I eat something, like crackers and maybe some fats and starches that the water that I was now drinking would be able to re-hydrate my body better. They also indicated that having more than 3 cans of RedBull in an 8 hour period can cause some people to hallucinate. Anyway, what I’m trying to say is that having water easily available is a good thing, especially of you are a moron like me. I recommend this product for morons and for those that care about hydration. March 20, 2012

Steve M: Laying flat and empty it is 17 1/2" x 6 1/2" - a bit less when full. A good 2 - 3" when full.

A functional bladder but, I find it too bulky for my Klim Badlands jacket which has the bladder pocket on the inside.

A shopper asked: G day, does this bladder fit into the klim badlands jacket ? Thanks. Dec 13, 2012

Steve M: Fits in the pocket under the back pad. If full, makes the jacket way too tight. Maybe half full might get by in a pinch.

In my opinion a poorly designed pocket in the Banlands jacket. Should be on the outside of the back pad and accessible from the back of the jacket rather than having to take the jacket apart from the inside to remove, and inset the bladder.

laavos: Yep.
The hose even snakes through the shoulder and exits on the left chest pocket.

Pretty snug fit though, you won't get the 3L out of it.
