Our Take

We carry the Highline Stretch Shell because it delivers the kind of dependable protection we look for when preparing for real mountain weather. Its stretch-enabled 3-layer build moves naturally on steep approaches and technical terrain, which makes a noticeable difference when you're climbing or skinning all day. The balance of durability, weatherproofing, and mobility is exactly why this shell consistently earns a place in our recommended kit for serious alpine travel.

Guide Pick™
Straight From The Source

Why We Love It
Jack Delany

Our guides choose the Highline Stretch Shell because it packs down incredibly small in a summit pack yet fiercely stands up to the harshest mountain storms. By pairing this rugged, lightweight weather protection with a dynamic stretch fabric, it completely eliminates the restrictive feel of traditional hardshells during technical, high-output climbs. It provides the exact uncompromising reliability and unrestricted mobility our team demands when unpredictable weather suddenly rolls onto the glacier.

“Black Diamond Highline Stretch Shell is a lightweight jacket that packs down small but can stand up to the harshest of storms.”
— Jack Delany, RMI Guide

Our Philosophy

We Simplify Outfitting

Whittaker Mountaineering was born out of the need for RMI to make sure their clients had the appropriate gear to get to the top of Mt. Rainier safely. After decades of trying, reviewing, arguing-over, and recommending gear, we can’t help but know what we’re doing by this point. We know what works, we know what doesn’t, and we use that expertise to stock our store. 

Who are these guys?

Black Diamond

Black Diamond has been outfitting mountain professionals for decades, building gear that’s tested on real climbs, not just in labs. We carry Black Diamond because their designs consistently deliver dependable performance where it matters most.
