Elite Tactical Performance. Now Built for the Heat.
The TD Operator Shirt (OSS) - Short Sleeve brings the same high-performance design of the OSS platform into a lightweight short sleeve tactical range shirt built for hot weather training, range days, and high-output missions. If you are looking for a similar base layer and something with merino wool, then check out the TD Base Layer Short Sleeve Performance Tee.
Developed in the field and tested by US SOCOM, the OSS Top platform was engineered to handle heat, sweat, movement, and friction during demanding operations. The short sleeve version delivers the same performance-driven construction while maximizing airflow and mobility when temperatures climb.
Built from a high-performance nylon and ICE nylon blend with spandex stretch, this tactical base layer provides 4-way stretch mobility, moisture-wicking performance, and built-in UV protection. The lightweight pique knit fabric breathes easily while maintaining durability for extended wear under kit or during long days on the range.
The redesigned V-shaped collar protects the back of your neck from hot brass, sling rub, and plate carrier friction. Raglan sleeves and wrapped side body panels allow unrestricted movement during weapon manipulation and dynamic drills, while the athletic silhouette keeps the shirt streamlined under armor.
Instead of bulky shoulder pockets, the OSS Top uses low-profile tricot warp knit loop fields on both biceps for patches and ID without adding unnecessary bulk.
If you are searching for a tactical short sleeve range shirt, lightweight combat training shirt, or performance shooting base layer for hot weather operations, the TD OSS Top Short Sleeve delivers serious capability without compromise.
It is one of the most capable warm-weather range shirts we have built. Lightweight, breathable, and designed to move, it performs during long training days without sagging or stretching out.
Clean design. Elite performance. Built for serious shooters.
