We’re not going to say it will make your training run or speed ascent actually fun (as opposed to “fun”), but it will help. Stretch polyester/spandex panels down the sides and under the arms dump heat when you’re working hard uphill, and the mechanical stretch ripstop nylon body blocks the wind to keep you warm when you turn around to head downhill in a cool alpine breeze. Thumb loops and finger loops keep the sleeves down, and a rear pocket holds your energy gel or bar and turns into a stuff pocket when you need to de-layer.
