US Level 2 Underwear (top) - Black - Helikon

US Level 2 Base Layer (top) - Black - Helikon

The US LVL 2 thermal top from Helikon in black is a technical base layer designed to optimize protection against cold without compromising comfort during dynamic activities. Inspired by American military equipment, this top is designed for hikers, military personnel, security agents, or outdoor enthusiasts.

Thermal underwear for cold and active climate

Functioning as a first layer, this thermal top retains body heat thanks to an interior mesh structure that traps warm air while remaining lightweight. Ideal for mountains, long walks, or extended missions in cold weather.

Breathable fabric promoting moisture wicking

The 95% polyester and 5% elastane blend ensures good breathability. Even during sustained effort, moisture is quickly wicked outward, which prevents the wet feeling and improves body heat retention.

Fitted cut for total comfort and freedom

Its ergonomic cut hugs the body without restricting movements. The stretch fabric allows for easy layering of other garments while maintaining good thermal comfort and great mobility.

Discreet black color suitable for tactical uses

The black version is particularly well-suited to tactical, professional, or urban contexts. It blends into the outfit while remaining sober and elegant for daily use if necessary.
