The Atom LT is a necessity for anyone’s outdoor wardrobe and the Atom SL is like icing on the cake. Those late spring mornings or evenings where keeping your core warm on your climb, run, bike or hike is important and the SL is just the perfect answer. Love this vest and probably wear it and wash it more than any other single clothing item. Smart purchase for any active person.
