Description
Functional Base Layer for Tactical Use
The US LVL 1 Long Johns are purpose-built as a next-to-skin layer for high-mobility operations. Made from 100% polyester with Quick Dry fibers, they manage moisture effectively by wicking sweat away from the skin. Weighing only 160 g with a 130 g/m² fabric density, they offer lightweight comfort and minimal bulk for field use.
Material Technology for Optimal Drying
The specially engineered Helikon-Tex Quick Dry Knit structure promotes rapid evaporation – essential for high-output activities or extended missions. The fabric is durable, shape-retaining, and designed for repeated field wear. Flat seams reduce friction and prevent chafing.
Thermal Regulation in Layered Setups
These long johns help stabilize body temperature by preserving warmth during rest and dissipating excess heat during movement. The ergonomic fit makes them ideal for integration into a modular clothing system, providing base-level insulation without restricting mobility.
Practical Applications
Whether on duty, at the range, or in the outdoors – the US LVL 1 Thermal Long Johns are a versatile base layer. They perform well as part of a layered system or on their own under lightweight apparel in shifting conditions. Their low weight, maintenance ease, and performance make them a solid choice for extended deployments.

US LVL 1 vs. US LVL 2 – Which Thermal Pants Fit Your Mission?
Helikon-Tex offers two thermal pant variants – US LVL 1 and US LVL 2 – each tailored for specific climate zones and activity profiles:
- US LVL 1 is the preferred choice for warm to moderate climates and high-intensity movement. With a lighter fabric weight (130 g/m²) and superior moisture wicking, it excels during marches, field exercises, or as sun protection when worn as a standalone layer.
- US LVL 2 is engineered for cold to very cold conditions and lower activity phases. The heavier construction (220 g/m²) delivers solid insulation while maintaining breathability – making it ideal for winter bivouacs, guard duty, or alpine missions.
Both models are fully compatible with the Helikon-Tex layering system – the choice depends on temperature, activity level, and mission duration.
