Buck Mason’s 'Toughknit Thermal' brings vintage craftsmanship into modern wardrobes. This heavyweight long-sleeve thermal is meticulously knit, cut, and sewn in the brand’s own Pennsylvania factory, using American-grown ring-spun cotton for an authentic, heritage-inspired feel.

The Toughknit Thermal is crafted with Buck Mason’s signature Toughknit fabric, designed for durability and comfort. The material offers a smooth drape, while the rib-bound collar ensures lasting structure. Each shirt undergoes a double-wash process, giving it a soft, broken-in texture that feels as good as it looks. Cut with a classic fit, this thermal is ideal for layering or wearing on its own.

Available in three versatile colors, the Toughknit Thermal combines rugged utility with elevated design, making it a must-have staple for cooler weather. The product is now available at buckmason.com. Durable, comfortable, and undeniably stylish, this thermal defines modern craftsmanship.
