Weight & Packability
The Platypus Hoser’s minimalist design makes it the lightest and most packable of all of the bladders we examined that embody a hose system. Weighing simply 3.6 ounces, it’s practically as mild because the VectoX, which doesn’t have a hose or chew valve. It additionally rolls up and packs all the way down to a compact measurement of 9 by 3.5 by 1.5 inches, together with the hose.
It achieves its mild weight by way of a simplified design. The twist cap opening measures lower than an inch vast, whereas these on the Camelbak Crux or Cherainti Bladder will be as much as 4 inches in diameter. Its options are restricted to the water bag, hose, and chew valve.
Ease of Use
To realize its mild weight, the Hoser sacrifices many options. The one which impacted our testing probably the most was its lack of a shutoff change on the chew valve to stop leaks. Whereas driving to a trailhead, we packed the hose and chew valve inside our backpack, guaranteeing that the uncovered mouthpiece wouldn’t contact the soiled ground of our automotive. Certain sufficient, the chew valve leaked onto a down jacket in our backpack, soaking the insulation. This shouldn’t pose a serious subject whereas mountain climbing, so long as nothing presses on the valve.
The hoser additionally omits options like a deal with for simple filling, inside baffles, or a inflexible backer to take care of its construction in a backpack. Nonetheless, it does embody a small loop minimize into the reservoir, permitting it to be suspended in a backpack. Throughout our testing, these different options appeared much less vital than the chew valve shutoff change.
Ease of Cleansing
The Hoser proved to be the toughest to scrub of all of the fashions we examined. It could possibly’t be turned inside out, and the opening isn’t fairly large enough to suit a hand inside for scrubbing. Fortuitously, Platypus does promote a particular reservoir cleansing package, which features a lengthy brush for scrubbing hard-to-reach areas.
With its small, twist-cap opening, the Hoser dried slowly. It took over seven hours to develop into moisture-free when hung up exterior within the desert. It can’t be turned inside out like some bladders that dry extra shortly.
Style
Apart from its light-weight, our favourite facet of the Platypus Hoser is its contemporary style. Platypus claims the Hoser to be “taste-free,” and we consider they obtain this higher than a lot of the different bladders we examined.
The Hoser tasted contemporary proper out of the package deal, in distinction to the Gregory 3D Hydro and the Osprey Hydraulics, which each have a definite iodine taste even after cleansing.
Sturdiness
Though we skilled some leaking from the chew valve, we didn’t observe any splitting alongside the seams or leaking from the twist cap threads. Over six weeks of testing, the Hoser has demonstrated sturdiness up to now.
Ought to You Purchase the Platypus Hoser?
The Hoser’s light-weight design and reasonably priced worth will appeal to minimalist hikers and backpackers who aren’t explicit about options. We additionally consider it tastes higher than a few of the pricier, feature-rich fashions just like the Gregory 3D Hydro and the Osprey Hydraulics. Whereas it’s barely extra liable to leaking because of the absence of an on-off change on the chew valve, most leaks will be prevented with correct care.

Hydrapak Contour Evaluate: The Contour retains its weight low whereas incorporating a number of further options. For one, its chew valve features a shutoff change that minimizes leaking. Additionally it is considerably simpler to scrub and dry, due to its sliding closure and talent to show inside out. Runners could admire the inside baffles, which assist forestall water from sloshing round. The Contour achieves all these options whereas including solely two ounces to the Hoser’s weight.
Platypus Platy Evaluate: When you admire the minimalist design of the Hoser, you may also benefit from the even less complicated Platypus Platy.
