Review on High-Quality 2L Hydration Bladder with Leak-Proof Insulated Sleeve - BPA Free, Ideal for Bicycling, Hiking, Camping, Hunting, and Running by Iration Ahim

I like the product, I really like it; It's durable, well built, easy to use and fits my camel. But... The stiffness and/or the position of the neck (and maybe its sufficient size) does not allow to fill the tank more than 3/4. Then, when everything is ready and needs to be dried, it is very difficult (read: almost impossible) to remove all the water after use. I had to find a way to keep it open, using wooden spoons on the sunlit edge of the window to drain all the water and prevent mold from forming after each use (found this out after the first use when mold started to form ). Maybe a smaller hole. or a hole at the top would help. Good value for money but not for the design.
