Summary:
The Arc’teryx Gamma MX Softshell Jacket is good at what it does — act as a moderately wind- and waterproof soft shell with good mobility and a flattering fit. While it will not stand up to very cold temperatures, the fleece lining will keep you cozy in the fall and spring and on mild winter days. People looking for an all-around ski shell may be disappointed, as the slim fit does not accommodate layering and the price is steep, but for high-output activities on cool days, this jacket is comfortable and appreciated for its durability and comfort.
