Description
Insulating Base Layer for Cold Conditions
The US LVL 2 Thermal Pants from Helikon-Tex are designed as a functional base layer for cold weather. Serving as the first line of defense in a layering system, these pants sit close to the body and offer effective insulation in low-temperature environments. With a weight of 280 g and a fabric weight of 220 g/m², they deliver warmth and flexibility without excess bulk—ideal for tactical operations, winter outdoor activities, or cold-weather training.
Material Composition for Thermal Comfort
Constructed from a polyester-elastane blend (95% polyester, 5% elastane), the pants offer a soft feel, durable stretch, and excellent moisture transport. The thermoactive fabric draws sweat away from the skin, keeping the wearer dry during extended use. Smooth against the skin, the material prevents chafing and irritation—making it a reliable companion under uniforms, shell pants, or insulated outerwear.
Ergonomic Fit and Layering Compatibility
With a close-fitting cut, the US LVL 2 Pants are optimized for layering. They reduce bulk under additional clothing layers while maintaining mobility and thermal performance. Their elasticity allows them to adapt to the body’s movements, whether marching, climbing, or staying stationary in low temperatures.
Field Use and Practical Benefits
Engineered for demanding winter conditions, these pants are ideal for cold-weather marches, alpine operations, bivouacs, or static assignments with low physical output. Their quick-drying, moisture-wicking properties improve operational readiness in challenging environments. As part of the Helikon-Tex layering system, they offer essential thermal protection with minimal weight.

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.
