The opening decides whether it dries; the liters only decide weight · review
The most completely specified reservoir on this shelf: a 3 liter TPU bladder with an opening stated to admit a hand, a plug-in quick release with an auto-off valve, a baffle wall and a stated pressure figure.
Three liters, a food-grade TPU film stated tasteless, non-toxic and BPA-free, an insulated hose of 104 cm (40.9 in), a soft silicone bite mouthpiece with bite-to-drink and pinch-to-lock, a plug-in base connector with quick release and an auto-off valve, an improved double sealing technique with a 220 kg (485 lb) pressure claim, a central baffle wall, and an opening stated to be wide enough for a hand.
Most reservoirs on this shelf publish a capacity, a material word and a hose length. This one publishes the valve, the two shut-offs, the coupling, the sealing method and the internal structure. Those are the parts that fail, and they are the parts the hub compares on.
Fill port width. A hand is a useful image and not a dimension, and brushes are sold by size.
Hose internal diameter. Nine reservoirs in this family, no diameters. The 104 cm length tells you the tube reaches from the pack to your mouth, and nothing about what fittings it takes.
Empty weight. Nowhere. Three liters of water is three kilograms; the film underneath it is worth a number.
Check that your pack has a hanging point the reservoir can use, and check that the base connector clears the bottom of your reservoir sleeve — a plug-in fitting needs a little room below the bladder that a plain hose does not.
The American Amazon store returned nothing, so the buy link opens a local search rather than a page that is not there.

It closes the reservoir when the hose is unplugged, so the bladder can be lifted out and refilled without the tube dripping into the pack. Together with the quick release, it is the arrangement that stops a refill being a five-minute job.
A three-liter bladder holds three kilograms of water that moves when you do. The maker states a central wall that reduces that movement and keeps the reservoir flat, which is a running and cycling concern more than a walking one.
No. Not published on the listing — stated to admit a hand and ice cubes, without a figure. What the listing does publish instead is the film material: TPU, stated food-grade, tasteless, non-toxic and BPA-free, and stated by the maker to be safer and more durable than PEVA.
7.8/ 10
The reservoir that answers the most questions on this shelf. Only the fill port width, the hose bore and the weight are left open.
A running or riding pack where the hose comes off at the base for every refill and the reservoir has to sit flat.

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
