Valken’s V-TAC Headwrap is made from moisture-wicking material with a breathable mesh liner. The headwrap also features a sweat absorption panel with padding, and a full-length tie in the back for adjustment.
The Valken website features the Headwrap in Marpat, Black, Tiger Stripe, and Woodland, although various vendors seem to be selling it in V-Cam (read: MultiCam) as well.
