The Adidias Terrex Swift Mountain Summer is a summer-weight softshell hoody designed for high-output use while wearing a helmet and harness.  

Weather Protection
For its unusually thin fabric, the Adidas Mountain Summer jacket served up awesome wind and rain protection. It’s a light shell for milder conditions, but was more than capable of managing gusty winds and brief cloudbursts.

Breathability
Good breathability and superior moisture management combined to keep us cool, even when on sunny approach hikes. The excellent wicking performance of the Adidas jacket’s main fabric was one of my favorite features, and I also used the Mountain Summer as a mid-layer on colder climbs.

Mobility/Comfort
The Mountain Summer Jacket sports just enough stretch in just the right places to satisfy the vertically-inclined, and its hood (both with and without a helmet) remains one of the most comfy I’ve ever tested.

Weight
While 16 ounces sounds a bit chunky for an aerobic jacket, this piece adds an excellent hood, ergonomic adjustments, and a heap of all-around functionality that’s worth the weight.

Attention to Detail
Aside from its annoying bagginess at the wrists, the Adidas Mount Summer got all the little things right. Though the finish is nothing fancy, everything is well-placed and useful.

Value
The Mountain Summer jacket is priced like a casual windbreaker, but delivers serious alpine capability. A good value for almost anyone; a stellar value for alpine climbers.
