Propper has a new wind-blocking shirt that's worth checking out.
The Packable Full-zip Windshirt is a "quality solution for those seeking a wind barrier, whether worn under a soft shell or as a sole garment," according to Optactical.com.
It packs into own pocket for easy transport and features a water-resistant fabric for damp conditions. A low-profile hood stows into the collar.
It's available in coyote, olive and black and will cost you $49.99 at Optactical.com.
