water bladder is made by TPU Material, high strength, durable
Can withstand the water temperature range : -20 to 50 degree Celsius.
The bladder itself seems durable and good quality, but where they say to put it in the backpack makes me weary of using it. I carry a variety of stuff in the backpack, but it all puts pressure on the bag since it is between you and the bag. I think it would be safer to just put it in the second large pocket, but then you lose room. It seemed like a great idea when I bought it, but I just don't trust it not to rupture in its designated pocket. If I used it more I would probably give it 4 stars, but as is I regret buying it. It's not worth the price to me.
Got it for my backpack works great.
Exactly as expected
still trying to get the smell out but all in all, it works well.
Pieces are not tightly fitted there are gaps and when I try to drink from it it sucks in air from the environment allowing the water not to come out well.
Like the backpack, everything all good.
Large bladder and look forward to using it in the back pack it was ordered with
