37.5®
37.5® technology uses natural active particles made from volcanic sand and coconut shells to regulate moisture and heat. They accelerate the evaporation of perspiration and help the body maintain an ideal microclimate cool when warm, and warm when cold. The effect remains permanently active, wash after wash.
REPREVE®
REPREVE® is an innovative fiber made from recycled plastic and industrial waste. It offers the same strength and durability as new polyester but with a much lower environmental impact. REPREVE® is a trademark of Unifi, Inc.
CORDURA®
CORDURA® is a strong, abrasion-resistant textile that provides protection on critical areas such as knees and pockets. It is shape-retaining, dirt-repellent, and designed for long-term use. CORDURA® is a trademark of INVISTA Inc.
