An under the helmet, under the hat, balaclava with full neck to nose, to the top of the head Dynamax fabric coverage the Seirus Dynamax Hinged Headliner is thin, warm, wicking, super-stretchy, and wind blocking, for a premium protective experience out in the cold. The hinged construction gives you the ability to tuck the cheek and nose protection under your chin without pulling and stretching the cover, for a comfortable fit without binding. Wear this up under a helmet, fold the hood down and wear this as a neck gaiter, bundle up for full coverage with up to the nose and down to the eyebrow protection, this now has more stretch, more warmth, more wicking, and more wind block in a still thin and flexible liner. To get the protection you need you don’t need thick and fluffy gaiters that get in the way of zipping up your jacket (which rather defeat the design of “staying warm and covered”) nor put up with thin liners that fit under your jacket and helmet but offer no wind protection to speak of. Get it all in a liner you can comfortably wear three ways for a complete through-the-season system that will take you from a winter windy blow to the beginning of the spring mashed potatoes. Flatlock seam construction for a shaped, streamlined, fit you’ll feel comfortable in when the weather it at its worst.
