I was caught off guard by the fact it just had a hole in the cap top. studying designs further, I found that that indeed is the gist of what the canteen top has. mostly, I was expecting some sort of system that would only allow water flow if a specialized drinking tube like that found on the Czech m10 was inserted. I really is decent quality, but just wasn't what I was expecting.
Perfect fit for the drinking tube
Works fantastic with the gas mask drinking tubes sold here too. Canteen is made of thin plastic, allowing you to fold it a little so it takes up less space in a bag. While that is a positive, I'm a little wary of the longevity of this product because of that fact. If it were full of water and fell on a sharp rock, it could certainly puncture. Other than that, excellent product.
You can put this in a regular canteen holder and use it like that or attach it to a gas mask. I think they're really cool and you don't see them too often. I picked a couple up because they are pretty good price for the quality.
Works great, also can be used as a regular canteen. The hole in the top is the perfect size for the gas mask drinking tube
I'm so glad I got this. I love wearing my gas mask simply because it looks cool, but I get thirsty in there. This along with the drinking tube has solved that problem!
