The women's Addison LS is a soft, plaid flannel shirt with a contemporary style and performance construction. It's made from Pulaski™ polyester flannel, which is brushed for warmth and softness that dries quickly. Arc'teryx designed the Addison with a traditional front button placket and outfitted it with two identical chest pockets that secure with snap-button flap closures. It comes in regular fit, which combines clean exterior lines with a comfortable and natural appearance over a t-shirt. Articulation in the sleeves and gusseted underarms improve the tops' freedom of movement during cycling commutes to the office and evening strolls around the city.
