Solid and Reliable
by Alex M (5 out of 5 stars)
March 30, 2016

I've purchased two of these now - the first developed a large leak when the bottom seam began to break after a year of heavy use and abuse. Probably the sturdiest hydration bladder on the market, and at a price lower than many other options. Only complaint would be the heavy black rubber tube means your first sip of water on a sunny day will be a hot one.

Well its the real deal for sure. I will say there was nothing sealing the package so it may have been taken out and put back in but I can tell it was not used. Im very satisfied with it and its half price of milspec with improved capability and still milspec. This is old stock (mine dated 2005) before camelbak added big bite valve covers so if you want one itll be another $8 but its worth it

Solid build, highly recommend.

Chemical resistant, solid build, namebrand, and a very good price. Mounts to my Avon Protections Gas Mask flawlessly, and considering Avon's version of this water bladder is the same exact one as this, only stamped with their name and marked up a lot. Definitely recommend.

Great water bladder hiking through questionable water sources

Very good water pack especially for hiking and camping, the chem bio is for getting the CamelBak wet and submerged in questionable water sources to hopefully prevent cross contamination of good treated water.

Perfect for when you're thirsty, and biological warfare happens to be all around you.

Built well, not a chintzy fake knock-off. Perfect for my bladder provisioned vacation bag. Interestingly, TSA always lets me through with 3L of water.

This was another piece I added to my personal protext I've gear collection. Having a water source is critical in every environment. Having one in an nbc situation is even more so. Great product.
