Wore this on a chilly morning hike and it kept my core toasty while my arms stayed free to move. The recycled nylon shell has a nice dry feel to it, not that shiny slick stuff, and it stuffs down small enough to toss in my daypack.
Wore this over a hoodie on a windy 40-degree hike and stayed toasty the whole time — the high-loft down really does its job. Love that the shell is made from recycled fishing nets, and the shorter cut keeps it from feeling bulky.
