Arc'teryx Ionia Merino Wool Shirt SS

The Ionia Merino Wool Shirt SS is a lightweight, soft short-sleeve shirt made from fine Merino wool wrapped around a nylon core for added durability. Merino naturally helps regulate temperature and resist odour, while the breathable, air-permeable fabric keeps it comfortable across changing conditions.

Its streamlined fit and articulated patterning support unrestricted movement on hikes, runs, tours and treks. Responsibly sourced wool, Fair Trade Certified™ production and versatile mountain performance make it well suited to active men who value natural next-to-skin comfort and durable construction.
