Helikon US LVL 1 Long Johns - Olive Green
The Olive Green thermal leggings Helikon-Tex are designed to be worn as a base layer directly against the skin. They serve as a foundational component of the U.S. Army’s ECWCS (Extended Cold Weather Clothing System). Made from lightweight and durable Helikon-Tex Quick Dry fabric, they efficiently wick moisture away from the body to keep you dry and comfortable.
Thermoactive Quick Dry material
The leggings are made from Helikon-Tex Quick Dry thermal knit, composed entirely of polyester. The fabric dries quickly and efficiently wicks moisture away from the skin, providing thermal comfort even during intense physical activity. A specially engineered fiber structure enhances evaporation efficiency. These base layer leggings work well with other ECWCS garments or thermal wear, making them ideal for cold and transitional weather conditions.
Well thought out cut
The long johns feature elastic bands at the waist and ankles, ensuring a snug fit and helping retain body heat. The fabric and ergonomic design allow full freedom of movement. A traditional fly is included for convenience. Flat seams help reduce the risk of chafing.
