Useful bedside water bottle for easy sipping

Using a water bag as I’m recovering from a treatment and need constant hydrating. The bag holds the water well and it is easy to extract water for drinking. Cheap and good!

manufacturing issue - second bladder leaking

having a bladder leak halfway through a half marathon...not the greatest joy... (nothing was in the back of trail run backpack to justify a puncture either)

A bargain beauty!

For a fraction of the cost of similar products, this worked perfectly with no issue. My daughter chewed through her mouthpiece but it still works and didn't leak.

Food grade plastic must be used

Every thing is good ... problem is it smells like plastic when you drink water it stinks... Food grade plastic should be used

good for abit

loved everything about it, the ease of filling, the ease of drinking and filling, no weird taste but this is the second one to have a leak by the side of the bladder

Functional and affordable!

I see many people complaining that the mouth piece should have a guard on there because it drags along the ground while they hike - get the appropriate backpack and you wont have that issue. This product is way cheaper than others on the market and works just as good. The great difference if the way you fill it up with water - you can clean the inside so much easier for a longer lasting product! I went snowboarding with is all day and had no issues.
