ガイドエアフリース

Wore this fleece on a chilly morning hike and it breathed way better than my old pullover, no clammy feeling when I worked up a sweat. The warmth-to-weight ratio is honestly impressive for how packable it is.

Wore this as a midlayer under a shell on a cold morning climb and it breathed way better than my old fleece, no clammy feeling on the uphill push. It's thin enough to stuff in my pack but still warm when the wind picks up.

Pulled this on for a hike in windy 40-degree weather and stayed warm without overheating once I got moving. The breathability is spot-on, and it's light enough to stuff in my pack when the sun came out.
