Description
Technical Base Layer for Reliable Thermoregulation in Demanding Conditions
The Helikon-Tex Underwear Top US LVL 2 is engineered as a thermal base layer for cold to shifting weather environments. Its blend of polyester and elastane delivers functional performance through excellent breathability, flexibility, and insulation. With a fabric weight of 220 g/m² and a total weight of 339 g, this lightweight top integrates seamlessly into tactical layering systems, making it ideal for cold-weather operations.
Controlled Heat Management and Field Performance
Thanks to its thermoactive fiber composition, the US LVL 2 top ensures effective heat release during periods of exertion while minimizing thermal loss during rest. This balance of insulation and ventilation makes it a reliable choice for extended missions. The quarter-length front zipper allows for individual adjustment of body temperature and moisture control – especially useful in changing activity levels or terrain profiles.
Fabric Construction and Wear Comfort
The polyester-elastane fabric blend (95% polyester, 5% elastane) features a smooth outer surface that enables friction-free layering beneath outer garments. Its moisture-wicking capability draws sweat away from the skin, reducing the risk of chilling. In addition, the fabric dries significantly faster than conventional materials – an operational advantage in wet or humid environments. Its ergonomic fit provides close-body contact without restricting movement, ideal for dynamic use within a modular clothing system.
Operational Versatility and Application
Designed for military, law enforcement, and demanding civilian users, the Underwear Top US LVL 2 excels both under protective shells and worn solo during recovery phases. Whether during winter patrols, alpine bivouacs, or tactical deployment in cold climates, it forms a reliable foundation for any cold-weather apparel configuration. Its easy-care durability ensures it retains form and function even after repeated washing and field use.

US LVL 1 vs. US LVL 2 – Which Base Layer Fits Your Mission?
Helikon-Tex offers two functional long-sleeve shirts – the US LVL 1 and the US LVL 2 – each tailored for specific environmental conditions and operational demands:
- US LVL 1 is the ideal lightweight base layer for warm to moderate climates. With its low weight, high breathability, and UV protection, it's perfect for summer patrols, physical training, or active movement under sustained conditions.
- US LVL 2 is the go-to option for cold or variable weather. It provides additional insulation, a close ergonomic fit, and a 1/4-length zipper for precise thermal and moisture control – ideal for alpine missions, winter operations, or bivouac use with lower physical output.
Both shirts are thermoactive, quick-drying, and optimized for layering systems – the key factor is the ambient temperature and level of physical exertion during the operation.
