When the weather turns midday or you’re starting in the dark, you need a go-to layer to keep the chill out without overheating.

We made this intentionally simple. At less than 2 oz (size M), it pulls far above its weight, with premium Pertex Quantum Air fabric that breathes during a sweaty pursuit without compromising wind resistance. Its textured yarn remains soft on the skin while also layerering nicely in harsh conditions, and its DWR finish sheds light rain or snow. Elasticized hood and cuffs and a simple cinch closure on the bottom hem keep it snug when you’re working hard.

This ultralight, versatile windshell is designed for high-output days when breathability is just as crucial as wind resistance. Stuff it in a pocket as an emergency shell, wear it all day on a windy ridgeline scramble, or throw it on before a quick descent - our Crest Windshell goes anywhere you do.
