US Level 1 Underwear (Long Johns) - Black - Helikon

The Helikon US LVL 1 leggings in black version are an effective thermal base layer for physical activities in cool weather. Lightweight, breathable and comfortable, they ensure excellent moisture management while remaining discreet and versatile for tactical or outdoor use.

Lightweight base layer designed for intense activities

This undergarment is designed to offer light thermal insulation while facilitating mobility. Perfect for hiking, trekking, or intense training, it limits heat loss while maintaining good thermal comfort.

Quick Dry breathable fabric with fast drying

Its 100% Helikon-Tex® Quick Dry polyester mesh allows rapid sweat evaporation. This prevents stagnant moisture in contact with the skin and keeps you dry, even during prolonged effort.

Flat anti-irritation seams for more comfort

Flat seams effectively prevent chafing, even during prolonged wear or under fitted clothing. This is an essential detail to ensure comfortable wear during several hours of activity.

Discreet black color suitable for all environments

Black offers great discretion, whether in a tactical, professional or civilian setting. It combines easily with other clothing and adapts to all outfits, without compromising on functionality.
