FR Classic Longs

SKU: FR300400

Flame Retardant Classic Longs. Unisex.

This is a flame retardant version of our Classic unisex longs, made in a wool blend consisting of 51% Merino wool and 49% Viscose Lenzing FR.

This unique blend ensures excellent moisture transport and insulation performance. Perfect for use during moderate to high-intensity activities in cold and freezing temperatures. The 100% natural fibre composition means that the flame retardant properties do not diminish over time. Our flame retardant Classic range has been tested in accordance with EN ISO 15025 - EN ISO 11612. 

The Classic Wool collection is made from superfine, itch-free Merino wool. Garments are ultrasoft, highly durable and have a close, comfortable fit. At low temperatures, we recommend combining Classic Wool with a Super Thermo or Wool Thermo baselayer for optimal moisture transport and insulation.

Our goal is not to become the biggest brand in the market, but rather to encourage responsible consumption and work with our customers to protect the environment. We are acutely aware of the need to lower consumption rates to preserve nature and future life on the planet.
