A stretchy and deluxe softshell, the Gamma MX Hoody is an ideal piece for activities that require a lot of movement and a little extra weather protection. It earns high marks season because of its lavish comfort and competent wind and water resistance.
Performance Comparison

Weather Protection
The MX designation on this shell stands for 'mixed weather,' and that's where it excels. The Gamma MX provides mixed usage protection in changing weather conditions. It sheds water for a time and blocks a decent amount of wind, though it won't shelter you from a severe storm or downpour. In that situation, you would want a hardshell. Outfitted with a DWR finish that beads and sheds water, and a hood that cinches down to block against windy weather, this jacket is a solid performer through all kinds of cold and windy swing season activities. If you want to add a softshell to your wardrobe that you can feel confident about and that will last for many years, this is a fantastic choice.
The Gamma MX was able to withstand squeezing through slot canyons from both a movement and a durability standpoint, all the while keeping our testers protected from all manner of weather variables.
Breathability
The Gamma MX is adequately breathable, particularly when you consider that it has a lining and is on the heavy side. It strikes an excellent balance between protection and ventilation — whether biking, skiing, running, or hiking in the glacial alpine, it allows the body to breathe better than most other lined options. As a bonus, if you are working hard and need more airflow, you can unzip the sizeable mesh-lined hand pockets to use them as vents, a helpful detail that we appreciate.
A steep hike up to a glacier in the winter really proved to us that the Gamma MX Hoody can not only handle some wind and low temps but also feel great when raising the heart rate.
Mobility
Mobility is another area where this shell excels due to top-notch tailoring. With underarm gussets, articulated elbows, and lush stretchy fabric, the Gamma MX is easy to move in and an overall joy to wear. It doesn't ride up when you raise your arms, and it moves expertly along with you during all types of activities. Whether hiking, cross-country skiing, ice climbing, or just running around town, this layer is comfortable and non-restrictive. When worn over a helmet, the hood is slightly tighter than on other models, but not enough to cause discomfort or irritation.
The Gamma MX was well-appreciated while navigating the unknowns of chilly Utah canyons.
Weight
The insulative lining of this jacket adds a bit of weight, landing the Gamma in the lower half of our test suite. However, at 17.1 ounces, we don't consider this shell so heavy as to be cumbersome. We have no reservations about recommending it for long days in the mountains. While it's considerably bulkier than other options in our review, the silver-lining is farm better weather protection.
The Gamma MX is on the heavier side, but it also offers excellent comfort and weather protection.
Versatility
The Gamma MX offers excellent features suitable to the ice climber, backcountry skier, or general swing season athlete. It has a slim and contoured fit that provides a flattering profile for all manner of activities, remote or urban. The helmet-compatible hood adjusts for volume in the back and around the face and features a stiff, laminated brim, which helps keep it firmly in place on a helmet. It also aids in blocking sun and rain from the eyes. It fits over a helmet fairly easily and also adjusts down to fit well over a bare head.
The hood on the Gamma MX is easy to adjust whether you have a helmet on or not.
The Gamma has four pockets — one laminated sleeve pocket, one garaged chest pocket, and two hand pockets. While it's a little tight, the hand pockets are indeed accessible if you're wearing a harness. The stretch-woven cuffs are not adjustable, so they can't be tightened around glove cuffs, but they do slide smoothly underneath gloves with a long gauntlet.
You know it's going to be a good adventure day when your jacket moves well, keeps you warm, and also allows you to get in your pockets with a harness on.
The construction quality of this piece is very high, with well-thought-out and useful details. It has a durable, thick wind flap behind the easy-to-use zipper that prevents snagging and that also blocks cold air from coming inside. The material by the face is a very soft fleece which prevents chin chap when the hood is cinched down. The fabric is easy to keep new-looking, and the available colors are fun and appealing. We felt at ease, natural, and even a bit classy wearing the Gamma MX from the mountains to the grocery store to drinks with friends.
Value
This is the most expensive jacket in our review, making it a commitment to purchase. However, paying a luxury price for an excellent item can be worthwhile. This piece is exceptionally comfortable, which is one of the main things you want in a softshell. If you decide to throw down and purchase the Gamma MX, we don't think you will be disappointed. Making your investment even more worthwhile is the fact that this jacket is extremely durable, and the classic look is likely to remain stylish for years to come.
Even when we couldn't get to the mountains we loved having the Gamma MX around for things like cold urban bike rides and general commuting.
Conclusion
A high-end softshell, the stretchy Gamma MX Hoody offers excellent weather protection, mobility, and comfort. We think this piece illustrates some of the best and most desirable characteristics of a cool-weather softshell.
Climbing, hiking, biking, skiing... whatever your pleasure, this jacket will be a welcome addition to your wardrobe.
