Description
Functional Base Layer for Active Use
Weighing only 167 g and featuring a material density of 130 g/m², the Helikon-Tex US LVL 1 shirt ranks among the lightest tactical base layers. It is intended to be worn as the first layer under jackets, shirts, or uniforms, but also performs reliably as a standalone piece during high-output movement or sun exposure.
Material and Construction
The shirt is made from 100% polyester using a Quick Dry knit structure that ensures rapid drying and efficient moisture transfer. Sweat is quickly moved away from the skin, keeping the surface dry and comfortable. The fabric is breathable, abrasion-resistant, and shape-retaining – ideal for load-bearing setups involving backpacks, vests, or plate carriers.
Thermal Regulation and Comfort
Thanks to its thermoactive properties, the US LVL 1 shirt helps balance body temperature during changing activity levels. It preserves warmth at rest and vents excess heat when moving. Its close fit and low-friction seams increase comfort during prolonged wear – even in demanding conditions.
Field Applications and Use
As part of the Outback series, this shirt is optimized for trekking, tactical training, patrol duties, and long-distance movement. It works perfectly as a first layer in warm to moderate climates, protecting skin from abrasion and UV exposure, and packs compactly. Its easy-care build makes it a dependable choice for extended operations with limited access to garment maintenance.

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.
