Explore What Sets This Product Apart

Keep Warm & Protected

Enjoy the warmth and soft touch of our Brass Monkeys FR fabric, a blend of merino and viscose fibres. It allows your body to self-regulate its temperature while offering protection in hazardous workplace environments. Merino wool is naturally antibacterial, odour resistant and moisture wicking, keeping you fresh and comfortable all day long.

Flame and Arc Resistant Merino Blend

Our Brass Monkeys FR range is made of merino wool and FR treated viscose, enhancing the natural flame resistance of merino. Our fabric meets the ASTM D6413 and F1959 standards for vertical flame and arc flash protection, with an arc rating of ATPV 4.2cal/cm2 (HRC1). This helps reduce instances of fabrics catching fire or melting when exposed to a flame or an electric arc, and can protect you from severe burns and injuries.

High Visibility on the Worksite

Stay visible on the worksite or on the frontline with our bright orange colour. Perfect for those wanting to stay highly visible during the day*. High visibility clothing can help you stand out from your surroundings and alert others to your presence, reducing the risk of accidents and injuries.

*Does not contain fluorescent materials to support additional nighttime visibility.
