The FXR Boost Anti-Fog Balaclava delivers cold-weather coverage with an anti-fog design built to help maintain clear vision during winter riding. A full-coverage nose mask directs exhaled breath downward to help reduce lens fog, while laser-cut breath holes in the mouth vent improve airflow and comfort. Breathable, brushed mid-weight Omni-Stretch™ construction provides flexible coverage and a comfortable fit, while a windproof eyeport and dual-layer wind-blocking construction at the chin and neck help protect exposed areas from cold air. The flared shoulder area extends coverage beneath outerwear for added winter protection, and a silicone guide provides a dedicated eyeglass port. Select colors are available in three sizes for a more dialed-in fit.
