Dynafit Alpine Wind Jacket Men's Ultra Yellow XL - Ultralight Windbreaker for Trail Running

Featherlight at 125 g and packing down smaller than a fist, the Dynafit Alpine Wind Jacket redefines what a trail running shell can be. Where ordinary windbreakers add bulk and slow you down, this jacket disappears into its own chest pocket until the moment gusts hit an exposed ridge. The Dynashell Ultralight fabric—100% polyamide—balances windproof protection with high breathability, while a PFC-free DWR treatment shrugs off light rain and snow without harming the environment.

In daily use

Whether you're ticking off vertical meters on a trail run, pushing the pace on a mountain bike, or hiking a windy ridgeline, the Alpine Wind Jacket is the layer you'll reach for when the weather turns. The full-length front zipper allows quick ventilation, while the close-fitting hood stays put even in strong gusts. The jacket's packability means it lives in your running vest or hip belt, always ready when the temperature drops or the wind picks up. The athletic cut reduces flapping and drag, so you can focus on the trail ahead.
