Gear Review: Arc’teryx Gamma MX

Arc’teryx Gamma MX

by Shaun Nauman

The Arc’teryx Gamma MX is a softshell, used as a mid-later when used in conjunction with the Layering System. The Arc’teryx Gamma MX is a technical softshell designed for active use in inclement climates. The”MX” identifier stands for ‘Mixed’ use. A list of Arc’teryx identifiers can be found on the general information, here.

This wind-resistant, breathable Gamma MX is perfect for alpine specialists looking for enhanced mobility. A tough, highly wind-resistant outer face sheds moisture and a light fleece backer adds warmth while wicking away moisture. The Arcteryx Gamma MX is a moderately breathable, wind resistant and stretchy softshell designed for moderate output alpine and ice climbing. The jacket uses Fortius 2.0, a stretch woven nylon-spandex material, lined with thin fleece. It’s moderately wind resistant, comfortable, and unrestrictive. The five exterior pockets provide a ton of storage options. The fit is technical and slim and the hood is comfortable when I have owned the Theta AR for one year now. I use it as my primary mid-layer during the winter season in conjunction with the layering system for AT splitboarding in the backcountry. I use the Beta AR or Theta AR as my outer-layer.

As with all tech clothing, particularly shells – keep them clean. Build up of dirt, oils, sunscreen, etc. will cause the DWR and breathability of the 3-layer GORE-TEX® system to work less efficient.  See the tech clothing care guide directly from Arc’teryx for pointers on cleaning and renewing the DWR. As with all tech clothing, never use fabric softener.

Retail $350 USD

Curious about the Arc’teryx factory? “In total, a single jacket takes nearly six hours to produce—it will pass through about 80 sets of hands, that’s over 250 processes. Take into consideration the materials being used—space age fabrics and fastenings—and do a little math. You’ll find that an Arc’teryx parka (they go from about $300 up to $1000) suddenly doesn’t seem so outrageously priced. More…
