The Cutter Overshirt in Lighthouse Check

This overshirt lands somewhere between a heavy flannel and a light jacket, cut generously enough to throw over a thermal or tee without binding. The 12.5-ounce organic cotton twill holds its shape through the day and adds a layer of warmth without bulk, while the oversized silhouette gives you room to move and layer underneath.

The Lighthouse Check pattern—a muted grid that reads nearly solid from a distance—keeps the piece versatile enough for daily rotation. Chambray lines the interior of the cuffs, collar, and front placket, so rolled sleeves show a contrast fabric instead of raw edges. Two chest pockets close with buttons and sit high enough to stay functional even when you're wearing a pack or bag.

The fabric arrives pre-washed, so it feels soft and lived-in from the start rather than stiff and new. Double-needle felled seams reinforce stress points and lie flat against the body. Adjustable button cuffs let you dial in the fit at the wrist, and the California collar—wider and more relaxed than a standard camp collar—frames the neckline without stiffness.

You can wear this buttoned up on its own in spring or fall, or open over a long-sleeve base layer when temperatures drop. The weight is substantial enough to function as outerwear in mild weather, but breathable enough that you won't overheat indoors. Machine washable on cold with a low tumble dry.
