Built for guys who want the substance of a MuskOx flannel without the extra heft. The Naked Grand Flannel is our first-ever unbrushed flannel, leaving the 8.3oz/sq yard 100% cotton fabric in its naturally woven state. Without the added loft of a brushed finish, it has a lighter hand feel with more natural texture. The unbrushed surface also lets the character of the Portuguese weave come through -- revealing more of the detail, depth, and craftsmanship woven into every shirt.
