Recently traveled to Denver, CO and hiked up Longs Peak (a 14'er). All I had was this Quasar plus a Marmot Precip - stayed warm throughout without a second thought! Lightweight and packs into its own pocket ~ what else can you ask for?! Highly recommended (I am 5'9, 160lb, athletic build and the "small" fits well; the team red looks great too!)
