Cerium Vest

Story

Packable, lightweight goose down vest for alpine layering and standalone warmth

The Cerium Vest delivers exceptional warmth without the weight when the temperature drops. 850 fill European white goose down traps heat where you need it most, while strategic Coreloft™ synthetic insulation protects moisture-prone areas against damp conditions. Wrapped in a light yet durable 15D Arato™ recycled nylon shell, it serves as a streamlined alpine midlayer or a quick-deploying standalone during trail breaks and cool camp nights.

Features

• Down Composite Mapping™ places synthetic insulation in moisture-prone zones and high-loft down in core areas for optimized thermal performance
• Articulated patterning and a mid-height draft-sealing collar offer unrestricted mobility and seamless layering
• Packs tightly into the included stuff sack with quiet TPU zipper pulls and a built-in internal security pocket

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.
