Arc’teryx Kragg Lithographica Shirt Habitat. Crafted from heavyweight 240gsm combed cotton jersey, the Lithographica Shirt SS delivers a soft yet durable feel built for climbing and everyday wear. The relaxed fit is combined with gusseted underarms and shifted shoulder seams for unrestricted movement and comfort under a pack. A lithographica graphic print across the chest channels the brand’s climbing-inspired design language, while the rib-knit collar enhances durability and shape retention.
