If you're looking for a classic long-sleeved shirt, you can't go past the Kramer. Perfect for summer evenings, this version is cut in lyocell, so it'll keep you feeling cool and fresh in hot weather. Not only is lyocell drapey and ultra-soft, it's made by harvesting wood pulp from Eucalyptus trees, and doesn't use harmful pesticides and uses less water than cotton in its production. Good for you, good for the planet. Seen here in khaki.
