#Dont have Nozzle Cap

This product is good to use but it should be come with nozzle cap, so we can suck without any fear's. Decathlon kind resolve this issue ASAP.

Very convenient and weight balanced well.

Trekking bladder is a good addition and got rid of water bottles. Very balanced and easily accessible.

Drying problem

Its not possible to dry it from inside. We need to insert something which keeps its mouth open to let the air dry it.

Looks like something from space.

I sometimes wonder whether humans are assuming this is a hydration aid when In actual fact it is a musical instrument aliens use at betrothal ceremonies prior to sacrificing their Jedi prisoners to the sarlacc pit.

Not durable

This is a great size but lasted only 2 months (approx 7 hikes). The inner tube came away around the mouthpiece which resulted in it leaking my sticky electrolyte everywhere.

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!
