MKC x GRAYL GeoPress TI Purifier Bottle: Montana Tough Meets Easy Water Filtration

Throw it over open flames, scoop water from any stream, and filter water as fast as you can push a French press: Grayl’s bombproof GeoPress Ti was already a sturdy camping companion. Now the bottle gets upgraded with even more durability and easier filtering in the pricey but attractive MKC x Grayl – 24-ounce Geopress Ti Purifier.

This four-piece purifier set includes a Grade 1 Titanium exterior that’s tough enough to double as a cook pot on a stove. Fill the exterior with water, push the cartridge down, and Grayl says it can filter water from any sketchy source in just 8 seconds. This limited-edition collaboration includes a classy, laser-engraved gold logo from Montana Knife Co., and a couple of minor improvements.

Water Purification Tech: Grayl’s GeoPress Ti

Grayl’s GeoPress Ti impressed GearJunkie editors with its cool design, “fun as hell” usability, versatility as a cook pot, and usefulness abroad. The GeoPress Ti even won GearJunkie’s Best Water Filter Bottle award in the Best Backpacking Water Filters guide.

It uses electroabsorption and activated charcoal to purify water of sediment, bacteria, and other waterborne pathogens. Grayl claims it removes rotavirus, hepatitis A, norovirus, giardiasis, cryptosporidium, E. coli, cholera, salmonella, dysentery, and more.

It also claims that the charcoal goes beyond to filter out heavy metals, chemicals, viruses, and microplastics. GearJunkie testers appreciated the simplicity and fast filtering in previous tests: all it takes is a quick fill, press down, and you’re ready to sip.

Grayl states it can filter 24 ounces in 8 seconds, or 5 L per minute. Additionally, it says its cartridge lifespan lasts for 350 cycles, or up to 65 gallons worth of filtering. Replacement cartridges can be found through Grayl for $30.

Montana Knife Co. Gives Ruggedness Upgrade

So, where does Montana Knife Co. fit into this? This knife company swept the hunting world with authentic, gritty, purposeful blades. Each knife is made for living outdoors, and what’s imperative to a successful hunt or hike? Clean drinking water.

Grayl’s filtration system fits seamlessly with MKC’s mission to make good, hardy products, the Montana brand says. It also claims the collaboration marks a natural extension of MKC’s durability and Grayl’s inventiveness.

The exterior of the GeoPress TI is no joke: it claims to withstand a 10-foot drop onto concrete at full capacity. That’s thanks to the CP4 Grade 1 titanium that sports an impressive strength-to-weight ratio.

A black titanium PVD coating offers additional protection against abrasion, corrosion, drops, and flames, MKC claims. Plus, the coating may reduce friction while pressing down to filter, supposedly improving the ease and speed of filtration.

When you’re ready to make dinner on the trail, the titanium shell partners with the cook lid and a stove for a quick boil. In a pinch, you can even place the vessel into the coals of a campfire to heat up.

Butterfly handles on the exterior add ease to moving and pouring. The cook lid features a strain lid (in case you favor cowboy coffee) and a D-ring to remove from the hot pot with a stick or metal utensil.

MKC X Grayl GeoPress TI: Built for the Backcountry

Montana Knife Co.’s co-founder and Master Bladesmith, Josh Smith, promises to continue making products “for working people at a quality they can be proud of and a price they can afford.” While $250 for a water filtration kit isn’t unheard of, competitors offer filtration for much less. It’s also $30 more than the original version of the GeoPress Ti.

Hunters, hikers, and travelers abroad can all appreciate a versatile water bottle, and this one aims for both style and functionality.
