Diggin' in to Details

Our Take

This is the jacket that ends the debate on what to pack. Whether we’re heading up for a glaciated summit push or lapping powder in the backcountry, the Beta AR is the shell we trust to handle the abuse. It strikes that elusive balance of being tough enough to scrape against granite chimneys yet light enough to disappear in a pack. We particularly appreciate the stand-up collar, it creates a seal against the wind even when the hood is down, a small detail that feels like a luxury when you’re stuck at a freezing belay or transitioning on a ridgeline.

Guide Pick™
Straight From The Source

Why We Love It

When the weather turns and the mountain starts to test your resolve, this is the jacket our guides reach for without hesitation. The Beta AR has proven itself through years of hard use, from shedding relentless rain to sealing out high winds. It’s the rare shell that balances total protection with breathability and movement, which is why it’s become the dependable choice for guides who spend more days in the elements than the rest of us.

“"Arcteryx hardshells are expensive but are definitely a cut above the rest."

- Taylor Bickford”

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?

Arc'teryx

Arc’teryx has earned its place in alpine operations through decades of producing gear tailored to mountain professionals. At Whittaker Mountaineering, we carry Arc’teryx because when conditions get serious, their build quality, thoughtful design and materials stand up to the most extreme environments we climb in.
