The bladder is as great as advertised. So far has proven to be tough as nails in my ruck and the low profile design allows a good hydration amount without the size being so large that it takes up a lot of space or causes ruck loading issues. Would definitely recommend this product.
I have two of these bladders, one in each of my packs. They are incredibly durable and easy to refill, even with the bladder still inside a hydration pouch. The mouthpiece and cap are easy to use one handed and there is no strange flavor from the bladder. About to buy a third 3L low profile for another pack of mine A+ product.
This was the second source bladder I've bought. Their product is top notch. I had a minor issue with my hose and valve and a new one was shipped after a few email exchanges. Great customer service backing for a superior product.
I bought this the other day to use in my 5.11 back pack. It fits perfectly in the hydration bladder compartment. Love the antimicrobial linings and the slide seal for ease of cleaning. Got the UTA with it too so I can fill up on the go! Great stuff Source!
