Mdvora 1.5L/2L/2.5L/3L Hydration Bladder, 1/2/4 Pack Water Reservoir, Leakproof Water Bladder Hydration Pack, Large Opening Water Storage Bladder Bag, for Cycling Hiking Camping (2L,1 Pack Blue)

Great product

Impractical to fill and stops working when half empty.

So every single one of these bladders leaked where the pipe connects to the bag. I have a rod to hang all the bladders in the trunk and they all leaked water. I checked and double checked the attachment point which where fine. Unfortunately, the return window has closed and I will be trashing the bladders unless the seller gives me another option.

I purchased the 4 pack of 2L water bladders and they only hold 1.8L each. They are made well and work great but the capacity is 10% less than advertised.

I am so glad we chose the 3L size! On a hot day, the 3L of water lasted about 5 hours with heavy hiking. Upon first use, they did not have an unpleasant odor or strange taste. We refrigerated our water overnight, which worked out beautifully. Unfortunately, water bladders are difficult to share from. We encountered 2 people that did not have enough water with them and they were getting dehydrated. Praise God, we had a spare water bottle tucked in a pack. Carrying a spare each will now become an essential for our SAR team.
