Sturm Mil-Tec® Functional Underwear Performance Olive is a functional transitional-season performance thermal underwear set consisting of a long-sleeve thermal top and close-fitting thermal long johns. The model is designed for use as a base layer during physical activity, training, military and tactical tasks, hiking and everyday wear.

The combination of zoned construction, 4-Way Stretch technology, effective moisture management and antibacterial treatment helps maintain a comfortable microclimate next to the skin. The flexible material fits closely to the body without restricting movement.

Moisture Management and Thermoregulation

The material consists of 70% nylon, 24% polyester and 6% elastane. The synthetic fibers help move excess moisture away from the skin toward the outer surface of the fabric, where it can evaporate more quickly.

This structure helps maintain a comfortable microclimate during physical activity by reducing moisture accumulation next to the body and supporting effective thermoregulation. This makes the set suitable as a first layer in cool weather and during physical activity in moderate temperatures.

Zoned Functional Underwear Performance Construction

Functional Underwear Performance features a zoned structure with areas of different density and elasticity. These zones are positioned according to body movement and help provide an optimal close-to-body fit.

The flexible zones provide moderate supportive compression and help keep the thermal underwear securely in place during running, training, long-distance movement and other activities.

4-Way Stretch — Freedom of Movement

4-Way Stretch technology allows the material to stretch in multiple directions. This enables the thermal underwear to adapt to body movement during squats, running, bending and other active movements.

The elastane content helps the garment recover its shape after stretching and provides a close anatomical fit.

Seamless — Fewer Potential Chafing Points

The garment is constructed using Seamless technology, which minimizes the number of traditional seams. Flat, flexible connections are used where required and stretch together with the material.

This construction helps reduce the risk of skin chafing during extended wear and makes the set comfortable as a base layer underneath other garments.

Antibacterial Treatment

The material features an antibacterial treatment that helps limit the growth of bacteria associated with unpleasant odors. This is particularly useful during intensive training, long-distance movement and other forms of physical activity.

Thermal Top and Thermal Long Johns

The thermal top features a close-fitting anatomical cut and wide elastic cuffs that help keep the sleeves securely in place. The thermal top weighs approximately 210 g in size L/XL.

The thermal long johns also provide a close, flexible fit. A wide, soft elastic waistband helps prevent the long johns from slipping down and reduces localized pressure during extended wear. The long johns weigh approximately 290 g in size L/XL.
