The Armada Lassen Pullover is an excellent layering piece for so many adventures we can't even list them all in this little sliver of space. It's nice and warm, lightweight, and super packable. Have you ever been in a situation where the air outside is much colder than you want your body to be? Boom, toss on the Lassen and you'll be good. But wait, now it's warmed up and I'm too hot. No worries, take the Lassen off, stash it into your pack, and forget all about it until you're cold again later. It's low-profile, fits well under a hard shell, and looks clean cut and stylish on its own.
