Up on the Ice: Climbing Mt. Rainier with an American Mountaineering Legend

Gear Patrol, October 6, 2017

It’s 1:20 a.m. It’s cold and near pitch black. I’m somewhere around 10,200 feet above sea level, traversing the snowfield above the Cowlitz Glacier on the southeast flank of Washington’s Mount Rainier. Behind me, headlamps begin to ignite; their lights flicker in the distance as other climbing teams back at Camp Muir make preparations for the summit.  Continue Reading....

The Women Behind MtnLogic's Awesome New Mountain Wear

Outside Online, July 21, 2017

Dog-walking doesn’t generally push a waterproof jacket to its limits. But climbing Mount Rainier—especially as a working guide—has a way of revealing flaws in the gear. “Those details may seem like no big deal when you’re only wearing stuff occasionally,” says Jess Matthews, a guide at Rainier Mountaineering Inc., operated by legendary climber Peter Whittaker. “But when you’re wearing things day in, day out, the problems really become noticeable.” Continue Reading....

American Mountaineering’s First Family Launched an Outerwear Brand

Gear Patrol, June 23, 2017

For-athlete, by-athlete brands are not uncommon. The idea is a good one — athletes are constantly in the field, so they know what gear should be and what’s just superfluous — but in a saturated market, many get drowned out and overshadowed by big brands with big business acumen. Continue Reading....

Move Over Patagonia & Columbia, MtnLogic Takes Over Mountain Apparel

The Manual, March 5, 2017

Has your outdoor sweater been tested over 1.2 million vertical feet of elevation? Yeah, didn’t think so. Polartec isn’t a brand name you’d recognize like Patagonia, Columbia, L.L.Bean, or The North Face. But it’s the insulation company that’s been enlisted by all of the above to pack their jackets with the best warming/cooling power the outdoor industry has to offer. Continue Reading....

Peter Whittaker’s Quest to Make the Best Mountaineering Gear

Men's Journal, January 30, 2017

It's shortly before midnight, at around 10,000 feet on Mount Rainier, when a shooting star rips across the sky so close you can almost hear it sizzle. Groggy climbers are fidgeting with headlamps and harnesses on the edge of Cowlitz Glacier.

(RMI), knows every inch of them. Continue Reading....
