Engineered for fire resistance and optimal breathability in the field, the Arc'teryx LEAF Assault Balaclava FR is a lightweight head cover that can be worn with a helmet, eye and ear protection or an oxygen mask. The versatile balaclava features a flatlock seam construction to prevent chafing and irritation. It also has an adaptable design, which allows it to be worn fully exposed or eyes-only exposed, preventing eyewear fogging by increasing ventilation. It is made from 5.5 oz. TenCate Defender M mesh for breathability and is naturally flame-resistant. The fabric makes it perfect for vehicle operators and professionals working with heavy machinery that may cause incendiary hazards.
