The Long Sleeve You'll Reach for Between Seasons
Somewhere between a T-shirt and a sweater sits the layer you'll probably wear more than either.
Our Men's Royal Blue Heather Long Sleeve T-Shirt combines the easy comfort of your favorite tee with the extra coverage of a long sleeve. The rich Royal Blue color is softened by a subtle heathered finish, giving it depth, texture and a more relaxed character than a solid blue.
Made from a lightweight 60/40 combed ring-spun cotton and polyester blend, it's exceptionally soft, breathable and comfortable enough to wear on its own or layered when temperatures start to drop.
Jeans. Chinos. Under a jacket. Over absolutely nothing complicated.
This is everyday dressing made easy.

Royal Blue has always been a classic. Heathering makes it feel a little more relaxed.
The blend of cotton and polyester creates subtle variation throughout the fabric, giving Royal Blue Heather added dimension and a softer, lived-in appearance.
Pair it with faded denim and sneakers for the weekend. Wear it with charcoal or black for a cleaner city look. Add khaki or stone for contrast. Or layer it beneath a denim jacket, overshirt or casual coat when the weather cools.
Classic blue. More texture. Even more ways to wear it.
