Puts it where you want it

After using the straight valve for years and not knowing any better. I now have the angled valve on my hydro pack and it makes getting the valve to my mouth so much easier. Keeps my hands on the bars while mtn biking. Close valve is a must have. I don't know how many times the buddies would pack up only to arrive with all our camelbacks half full and everything soaked? :(

Great Accessory

I used this to add an extra reservoir to my CamelBak HAWG for my dogs. I added a removable extension tube using the Quick Link Conversion Kit and the Ergo Hydorlock Valve. The Quick Link allows me to pop the extension tube on and, using the Ergo Hydrolock without the bite valve, I can quickly siphon water into the dog's collapsible bowl without having to take my CamelBak off. It works great!

Finally no more leaks!!!

Simple, but effective! Weighs nothing and saves your single most valuable asset on any edventure, your water! I've used hydration packs FOREVER and while bite valves have improved, these little hydrolock valves really help a ton. Will never get a hydration pack without one.

Works like a charm

Get a few, without it your gonna get wet. without it and you cant refill your camelpack. It seems to fall off when taking of your pack cause It hooks on everything. the locking mechanism fall off.

Love my CamelBak

Love having the shut off feature for my pack. I actually purchased this as a replacement because the old one started to leak after about 6 years of usage.

Useful Piece!

This valve is a fantastic addition to a reservoir system. Keeps the bite valve from leaking. If only it came standard with the systems...

I wouldn't go without using it.

Before the hydrolock valve, my waterpack leaked. This is easy to use. I definitely recommend it.

Negative Reviews:

Backwards for use in winter packs!

The valve lever is in a nice compact position when open. However when in the closed position the valve lever is sticking up. This is an issue as you slide the valve in and out of the insulated pack (ie a winter pack with the valve in the shoulder strap). I find it ironic that camelbak would include this valve on any winter pack. I've been looking for a replacement (straight valve) to replace this. It's not fun having water freeze in the shoulder strap). This would be such a simple fix if the hole in the valve lever was drilled at a different angle.

Great product, but the valve can pop out leaking your entire bladder on the ground. I still use mine, but just note it's not fool proof. That being said, I recommend it.
