Arc'teryx Gamma MX Hoody Women's Softshell Jacket

$64.00~~$160.00~~

The Arc'teryx Gamma MX Hoody is a weather-resistant softshell built for mixed conditions and colder days, offering more breathability than a hardshell with just-enough protection for chilly hikes and approaches. Its hardwearing Fortius 2.0 softshell fabric pairs a fleece backer with wind resistance and a DWR finish, delivering lightweight warmth without the bulk of a fully insulated layer.

Taped seams, a helmet-compatible StormHood, elasticized cuffs and an adjustable hem draw cord seal out drafts, while articulated patterning and stretch fabric keep movement unrestricted on scrambles. A zip chest pocket and two hidden-zip hand pockets stay accessible while wearing a pack, and the FC0 DWR finish repels moisture without intentionally added PFAS.

How to use

Wear the Gamma MX Hoody as a standalone layer on chilly hikes and approaches, or as a midlayer under a hardshell on cold, wet-weather treks. Adjust the hem draw cord to seal out drafts, fine-tune the StormHood while wearing gloves, and use the zip chest pocket and two hidden-zip hand pockets, which remain accessible while wearing a pack.

Frequently asked questions

Is the Gamma MX Hoody suitable for skiing?

It is not specifically designed as a ski jacket, but its warmth, breathability and weather resistance suit high-output activities in cold temperatures, particularly dry days or uphill travel. As a softshell it does not provide the protection of a fully waterproof hardshell in prolonged snow, wind or wet conditions, and it can also be worn as a midlayer under a hardshell.

How should the Gamma MX Hoody be washed to maintain its water repellency?

Close the main zipper, open pocket zippers, release drawcord tension and loosen the cuffs. Wash on a gentle low cycle with a technical cleaning agent, then run a second rinse to remove soap residue. Tumble dry on permanent press low to reactivate the DWR, and re-apply a DWR treatment when water no longer beads.

Is the Gamma MX Hoody warmer than the Beta Jacket?

The Gamma MX Hoody generally feels warmer than the Beta Jacket. The Beta is a hardshell GORE-TEX jacket designed for waterproof protection, while the Gamma MX is a softshell with a poly fleece backer that provides light insulation and added warmth.

Can the Gamma MX Hoody be worn in winter?

Yes, it can be used in winter. Because it features a poly fleece backer as light insulation, staying warm depends on layering it with the right midlayer and baselayer.
