Source ConverTube Military Storm Valve – Tube with Accessories – Coyote Colour, One Size

Great colour and functionality. The drinking end opens with a pull and closes with a push instead of biting like simulate products, with a lid that protects it when not in use so can be sure of no wastage. Would definitely recommend.

Avid hiker, hunter, backpacker. I decided to take a chance on this product because I was so tired of having to essentially unpack and remove my bladder every time I wanted to fill water and hated having wet gear the one time that my bladder sprung a leak inside my pack. After making the switch I struggle to understand why bladders are even a thing any more? This system is well made and has a wide range of vessels it can attach to. A Nalgene or simple gas station water bottle weighs just as much or less than a bladder and allows for so much more versatility. It may not hold 3L of water, but bring another bottle that weighs 2 oz and you are covered. Perhaps my favorite piece of this system is the mouth bit. It seals well, is comfortable and efficient to drink from. The cap that covers it is amazing in keeping it clean and damage-free.This system on a bottle allows for several things that bladders do not:1) Bottles are much preferred for using during cooking. Trying to add water out of a bladder is cumbersome, both to remove from pack and to empty into cookware. A bottle you just pour or drink straight from.2) If you keep the cap for the bottle, you can share the bottle with others if needed as well as take in literally any other pack or standalone.3) What I think I find most appealing and somewhat funny, is that you can use it inside your pack just like a bladder, but now you can also keep in an exterior pocket of your pack and have easy access 100% of the time. That being said, a bottle outside the pack in cold temps means a possibility of freezing, but I'd rather have a cheap water bottle freeze and fail than an expensive bladder.Two points that I could see improvements on in future versions of this are:1) Hose Stiffness, the hose is very rigid and will take time for it to find its memory to each pack/system you place it in. That also being true for drinking, it is stiff and you have to put a little more effort into bending the hose to drink from... A small price to pay for durability though. I Believe this was designed for desert climates though so I am sure the hose loosens a bit when in the heat of the desert.2) The hose has a thin "cloth" sheath, which is awesome for glare and heat absorption of the hose and water within, but it lacks insulation, so in colder temps there is the chance your hose will freeze on you. Would like to see the neoprene hose sheath like other bladder models out there. Again, I believe this was designed with desert warfare in mind so insulation was not high on their list I imagine.All in all, I will be going this route for all future water system purchases. Bladders just don't cut it anymore.

The 63mm Nalgene adapter works perfectly with the MSR Dromedary 4L hydration bladder/reservoir. Solid construction, and it has a valve cup, which prevents it from getting dirty.

Perfect for hicking/backpacking. Once I played around with connections and learned how to open the mouth valve (find the dot & turn clockwise) water flowed easily. One added bonus is the mouth piece connection is universal so I can swap it out with my hydropack mouth piece.

Supports multiple bottles for your water solution.
