SD51 Water Reservoir Water Bladder Hydration Pack Storage Bag BPA Free - 1L, 1.5L, 2L, 3L. Running Hydration Vest Backpack

Good quality. I love the top fill. Allows for easier cleaning. Also like that the tube is detachable.

Used this in my backpack while marathon training. No leaks and held a lot of water

Almost perfect replacement bladder for the original camelbak.

The hose is fairly long but I tuck it into the front chest straps I then don't have to stretch or move my head to be able to drink.

This is a cheaper bladder, for the pros it does not leak, it is easy to fill and also easy to seal.

Easy to fill and clean. More importantly, no leaks.

Bought for a Duke of Edinburgh expedition for my 15 year old. We practiced filling up the water - there is a knack to it. Worked perfectly throughout the 3 days. Highly recommend

For the price this is a great replacement to the original. Does the job, spot on and fits my hydration pack well.

A practical, good‑value water reservoir that works well for day trips and longer outings.
