Wore it under my rain shell on a windy hike and my core stayed toasty the whole time. The down insulation packs a lot of warmth without any bulk, so layering over a hoody doesn't feel restrictive.

The down insulation in this vest is seriously warm for how light it feels. I threw it over a hoody on a chilly morning walk and my core stayed toasty the whole time.

Wore this under my shell on a windy ridge hike and my core stayed toasty the whole time while my arms didn't overheat. The down insulation packs down small enough to stuff in my pack when the sun came out.
