100% Merkalon Polypropylene. Made in New Zealand.
Wickability - Draws moisture and perspiration away from the skin, transferring it to the next layer, retaining a warm layer of air next to the skin.
Low Thermal Conductivitiy - means better insulation which keeps you warmer for longer periods.
Quick Drying - Because polypropylene is moisture repellant, a wet garment dries within a few hours.
Hard Wearing - A high resistance to rubbing, stretching or tearing.
Lightweight - Polypropylene is only 70% of the weight of an equivalent wool garment.
