Buck Mason just dropped an all-new lightweight double slub sweatshirt that feels like a tee but wears like a sweat.

Entirely made in the United States, it's 100% cotton slub on the outside and super-soft 60% cotton/40% rayon micro-jersey on the inside, which gives it warmth without adding onto the weight.  Each sweatshirt is also dip-dyed, which gives it that just-right worn-in look and feel.

Available now in four different colors, this is exactly what you need to take your summer style up a few thousand notches.
