Gamma Jacket

Story

A versatile, high-stretch softshell built for mountain movement

The Arc’teryx Gamma Jacket is the ultimate multi-tool for high-output mountain pursuits. Engineered with a durable, weather-resistant softshell fabric, it provides a crucial buffer against wind and light rain without trapping heat during a steep summit push. Its high-stretch construction and refined, articulated fit ensure that whether you're reaching for a hold or trekking with poles, your gear never holds you back.

Features

• Weather-resistant outer face sheds wind and light moisture during mountain scrambles
• High-stretch fabric and articulated patterning allow for unrestricted overhead mobility
• FC0 DWR treatment provides water repellency without the use of harmful PFAS
• Dual zippered chest pockets offer secure, accessible storage for small essentials
• Highly breathable construction prevents overheating during intense uphill pushes

Sizing

• The Gamma Jacket fits true to size. Take your usual jacket size.
• For the best personal fit, compare your body measurements to the size chart below

About

You may only know Arc’teryx from their pristine final products—but in our opinion, it’s all the hard work and experimentation behind the scenes that deserve an even bigger shoutout. From their homebase in Vancouver, every new jacket goes through a training regimen rivaled by the montage in Rocky IV—where it’s brought to the breaking point, refined, and refined again between rounds of high-tech lab testing and punishing field trials in Arc’teryx’s backyard, the British Columbian Coast Mountains. The end result is famously clean and functional outerwear that pushes the outdoor industry to new heights with every iteration. Seriously, GORE-TEX jackets would not be as lightweight and durable as they are today without the work these guys put in. Our picks from Arc’teryx are jackets and fleeces we’d feel comfortable wearing every day. Simply put, they’re as indestructible as mountaineering gear but also look put-together on your train ride into the office.
