The Dynafit Alpine Wind Jacket in Smoke Blue is a men's windshell weighing around 130 grams, built from DynaNylon Eco Ripstop at 58 grams per square metre. A windshell is not a rain jacket: it stops the wind chill that makes a sweaty climb suddenly cold, packs into almost nothing, and is meant to be pulled on and off repeatedly through a day.

• Around 130 g: light enough that carrying it costs nothing, which is the point of the category.
• DynaNylon Eco Ripstop, 58 g per square metre: a recycled nylon ripstop, so a snag does not run into a tear.
• Windproof, not waterproof: it will shed a passing shower and nothing more, so it is not a substitute for a shell.
• Alpine is the trail running line: the cut is close and short, made to sit under a running vest.
• Packs away small: the kind of layer that lives in the back pocket of a vest all summer.
• Recycled fabric: the Eco designation refers to the recycled content of the nylon.
