Sturdiness
In creating a water bottle designed to fulfill essentially the most intense filtration wants, Grayl realized the bottle wanted to have the ability to face up to the powerful environments the place water filtration is most related.
Made utilizing food-grade plastic and silicone, the GeoPress is constructed to deal with tough backcountry situations. In an instance of Grayl’s considerate design, a band of sentimental, rubbery plastic circles the bottle’s base to melt the blow of falls. We discovered this aspect efficient in our personal testing, observing how this bumper absorbed the shock of falls and deflected injury from the bottle. Placing it by way of drop checks onto rocky surfaces, the GeoPress got here away with nothing however minor scuffs, even when it landed on its aspect.
Design particulars and high quality building make the Grayl GeoPress one of the vital strong and sturdy bottles we examined. We’re assured this can be a long-lasting water bottle.

Ergonomics
Grayl created the GeoPress with intentionality, fastidiously contemplating how every design aspect improves performance and ease of use. This ends in a water bottle that adroitly blends type and performance.
The slim spout makes ingesting in movement simple and spill-free. A protecting cowl completely fastened to the lid screws over the spout to maintain liquid in and dust and particles out. All the lid is definitely eliminated for the addition of hydration mixes and ice.This additionally makes hand washing accessible – particularly essential for the reason that Grayl will not be dishwasher secure.
That includes a completely distinctive strategy of filtration (see Options beneath for extra particulars), the Grayl press methodology necessitates a multi-piece arrange (outer cup, interior press, lid, and air purifier cartridge). These components match and keep collectively completely, compacting right into a cylindrical form whose slim profile matches simply into backpack pockets.
The GeoPress’s filtration methodology is dependent upon urgent water by way of the bottle by hand, requiring some drive. To help, Grayl added rubbery grips on the lid and aspect of the bottle for non-slip urgent.
From prime to backside, every element of the GeoPress construct serves a objective and improves the expertise of utilizing the bottle to filter and hydrate.

Insulation
The Grayl will not be insulated. If you wish to maintain liquids chilly for a pair hours, take away the bottle’s lid for large mouth entry so as to add ice. Plastic water bottles lack insulation, in order that they’re normally extremely inclined to exterior temperatures. Throughout our testing, nevertheless, we have been stunned that the outer cup encasing the primary bottle of the GeoPress offered an off-the-cuff insulating layer. In contrast with different plastic bottles, chilly water stayed cooler for as much as an hour longer. Although it’s not designed to insulate, the outer cup offered some safety and slowed liquid warming.
These looking for efficient insulation for his or her drinks ought to in all probability look elsewhere. Nonetheless, Grayl’s multi-layered design provides it an edge over the usual plastic bottle.

Weight
Weighing 15.8 ounces, the GeoPress is heavy for a water bottle. Grayl’s main promoting level – its superior filtration functionality – prices it in weight. The conditions the place water purification is most related are sometimes backcountry utilization and whereas traveling- areas the place typically each ounce counts. For being a water bottle meant for these weight-conscious purposes, the heaviness of the GeoPress strikes us as counterintuitive.
Mountain climbing with the Grayl for miles over steep, uneven terrain, we rapidly seen its weight – each when crammed and unfilled. This proved a supply of discomfort after a couple of hours. We love this bottle’s sturdy construct and sensible press filtration methodology. Nonetheless, we will’t see ourselves utilizing this bottle as a water purification system for backpacking journeys, merely resulting from its heavy weight.

Options
Grayl affords the GeoPress in a couple of completely different colour selections in addition to in 16.9 ounce and 24 ounce sizes. These customization choices are lower than what many different water bottle manufacturers present. Grayl is much less involved with customized options and extra targeted on its specialty use as filtration water bottle.
A frontrunner within the area of interest of filtration, the Grayl exemplifies thorough and simple water purification. The GeoPress air purifier cartridge filters out protozoa, micro organism, viruses, chemical compounds, pesticides, and heavy metals whereas additionally enhancing water’s style, scent, and readability. Its filtration is unmatched by different bottles.
In different filter-capable bottles, unpurified water fills the bottle, passing by way of an inside filter in the course of the strategy of ingesting. That’s, water stays unfiltered till drunk. The Grayl makes use of a unique course of that may really feel acquainted to espresso drinkers who use an AeroPress or French press. Filling an outer cup with water, the interior press (or major bottle) plunges into the crammed outer cup, urgent water by way of the air purifier cartridge connected to the underside of the interior press. The result’s a bottle filled with filtered water that’s prepared for ingesting or sharing with a good friend in a matter of seconds.
A novel facet of the Grayl design is the air purifier cartridge’s one-way valve. This prevents liquid from flowing again into the cartridge, permitting for the usage of hydration mixes – one thing not potential with most filter bottles. The Grayl GeoPress tackles exhaustive water filtration in a model new method – a function we respect.
