My Oldest Arc Piece
A staple in my gear closet! Perfect for skiing, climbing, and around town. Still have my original Atom from a decade ago, going strong! Stays warm as a midlayer with light wind protection. I always bring this on shoulder-season adventures.

Great Jacket For Low-output Activity Or Cold Days
I love my atom hoody! It has a flattering but also comfortable fit. I use it for very cold days or for more low-output activities such as belaying or slower moving activities. The material feels very light and it packs down small!

Classic For A Reason
When I don't know what puffy to bring, I bring the Atom. While it is maybe not the "best" at anything, it is great for everything, making it a trustworthy, versatile, and solid companion for just about any mountain outing. From winter ski touring to alpine climbs, and just as stylish in town after, this is the one puffy to rule them all.
