The opening decides whether it dries; the liters only decide weight · review
A 3 liter reservoir that names its film as PE/EVA and includes a neoprene hose cover and a hose brush, then leaves the opening, the valve, the fittings and the weight entirely undescribed.
Three liters, a PE/EVA film stated tasteless, BPA-free and durable, a claim of being completely tight and leak-proof, universal compatibility with rucksacks that have a reservoir provision, a neoprene hose, and a hose brush.
A named film. PE/EVA is an answer. BPA-free, which is what several listings here offer instead, describes something that is not in the plastic rather than what is.
Two accessories in the box. A neoprene cover for the tube and a brush for cleaning it. Both are things people buy afterwards, and both are things that stop a reservoir being abandoned.
The opening. Nothing. Not a type, not a width, not a word. On this shelf that is the specification that decides whether a reservoir survives, because a bladder that never dries properly is a bladder that gets replaced.
The hose fittings. No bite valve, no shut-off, no coupling. A neoprene hose is supplied and nothing is said about how it attaches or how you drink through it.
The weight and the seams. Neither published, and the leak-proof claim leans on the second of them.
Ask the seller what the opening looks like, and whether the hose detaches at the reservoir. Those two answers change the daily experience more than the three liters do.
The American Amazon catalog lists it with no seller standing behind the entry.

It names the film, which is more than BPA-free does — that phrase says what is absent, not what is present. PE and EVA are the common alternatives to TPU on this shelf, and naming them at least says which family of material you are holding.
Because it is the first cause of a reservoir being thrown away. A wide slide top can be turned back and dried; a narrow port cannot. With nothing published, that is a question you can only answer after it arrives.
No. Not published on the listing. What the listing does publish instead is the film material: PE/EVA — stated, and described as tasteless, BPA-free and durable.
8.4/ 10
The film is named and the extras are useful. The opening, the valve and the fittings are not described at all, which leaves the most important question on this shelf unanswered.
A pack that needs a straightforward 3 liter replacement, where the brush and the hose cover are the deciding extras.
Amazon reports what buyers took in the month before this page was last checked: at least 100.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.

2 L reservoir · large opening, type not named · hose supplied · almost nothing else published
A 2 liter reservoir sold with a hose, whose listing publishes the capacity and then almost nothing else — no opening type, no film, no valve, no fittings and no weight.
Best for: A replacement reservoir where the pack sleeve is the only constraint and the details are worked out on arrival.
3 L reservoir · two hoses, summer and winter · cleaning brush included · opening type not named
A 3 liter reservoir that ships with two drinking hoses and a cleaning brush — three items other listings sell separately — while naming neither the opening, nor the film, nor the valve.
Best for: Someone who wants the brush and the winter hose in the same box and will find out about the opening on arrival.
Two 2 L reservoirs, 70 oz each · 4 in screw cap, the widest port stated here · bite valve with on/off · quick-release with auto-lock · a neck gaiter supplied · no bore, no film named
Two complete reservoirs for sixteen dollars, with the widest fill port stated on this shelf at four inches — on a page whose wording appears under two other brands in this same group.
Best for: Two people, or a spare kept filled in a fridge, where price per reservoir is the whole decision
