Breathable and durable functional underwear for year-round use
Performance Base Layer under combat clothing and tactical equipment
The BW Under Shirt Short Sleeve KSK Used is an original performance undershirt from Bundeswehr Original surplus, developed for demanding operational conditions. It stands out for its high breathability, excellent wearing comfort, and high durability. Renowned German manufacturers such as Comazo and Hexonia produced these modern performance shirts specifically for the needs of the Bundeswehr and their personnel.
The undershirt is intentionally tight-fitting and close to the body to quickly wick moisture away from the skin. The functional material structure supports effective moisture management and ensures a comfortable body climate, even under intense physical activity. Thanks to its high breathability, the shirt can be worn comfortably even on warm days and is ideally suited as a first layer under operational clothing, body armor, or outdoor gear.
Whether for outdoor use, bushcraft, trekking, training, or everyday work—this performance undershirt delivers reliable performance all year round. As a base layer, it helps regulate body temperature and offers all-day comfort in both heat and cold.
Note on fit: The base layer is very close-fitting. For a more comfortable and slightly looser fit, we recommend selecting one size larger.
The delivered items may differ from the images but remain first-class in function and durability.
