The opening decides whether it dries; the litres only decide weight · review
A 3 litre 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.
The bottom line Generous in the box and thin on the page. The two hoses and the brush are real value; the opening, the film and the valve are all left unnamed.
Three litres, a robust and BPA-free material, a leak-proof design, a large opening for filling, a cleaning brush, an ergonomic soft mouthpiece, a summer hose and a winter hose, and a hanging arrangement for packs and vests. The maker also states its system was tested in the Austrian Alps, which is the maker’s statement about its own product and not a figure.
Two hoses and a brush. On this shelf an insulated tube is normally an accessory and a brush set is normally an afterthought. Having both included is worth more than several of the specifications that are missing, because they are things you would otherwise buy twice.
The opening. Called large, never described. This is the specification this family is judged on, because a reservoir that cannot be turned back and dried is a reservoir that gets replaced.
The film, the valve, the coupling, the seams, the weight. None of them named. The leak-proof claim rests on the seams and the joints, and neither is described.
Ask what shape the opening is, and ask how the two hoses differ. Both answers are short, and neither is on the page.

Catalogued on the British Amazon store with nobody selling it: the reference is there, the offer is not.
Nothing came back from the American Amazon store, so the buy link there opens a local search instead of a page that is not there.

Usually an insulated tube, or one that can be blown clear and cleared of standing water. The maker states one of each is included and does not describe how they differ, so it is worth asking before ordering if freezing is the reason you are buying.
It helps. A brush set is bought separately by most people within a month of owning a reservoir, and having it in the box means the cleaning routine starts on day one instead of after the first bad taste.
2 L reservoir · large opening, type not named · hose supplied · almost nothing else published
A 2 litre 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.
≈ 25 €
3.0 L reservoir · slide-clip closure · reversible for cleaning · bite valve, auto-closing · 130 g
The only reservoir on this shelf to publish an empty weight — 130 g — alongside a slide-clip closure, full outside dimensions and a bladder the maker states can be turned inside out to clean.
Best for: A pack where the reservoir has to be cleaned and dried properly, and where 130 g is a figure you want to know rather than guess.
≈ $45 / £41 / 35 €
2 L reservoir · screw cap · 100 cm detachable hose · heat-sealed EVA · 36 × 17 cm
A 2 litre EVA reservoir that publishes something almost nobody on this shelf does — how its seams are made — along with its outside dimensions, an auto-lock mouthpiece and a 100 cm hose.
Best for: A pack with a known reservoir sleeve, where the seam construction matters more than a wide opening does.
