Cool comfort under armour

Fed up with cutting the sleeves off your UBACS? The Invader Gear Combat Shirt Short Sleeve is built for it. A moisture-wicking knit torso sits comfortably under body armour or a plate carrier and eliminates the heat retention that makes long games miserable, keeping you cooler and drier when it matters.

Tough where it counts

The sleeves, collar and shoulder area are made from a sturdy 60% cotton, 40% polyester ripstop woven fabric that shrugs off abrasion from straps and slings while drying fast. The high collar protects your neck from debris and sling-belt rub, a small detail that pays off over a full day on site.

Ready for your patches

Shoulder pockets close with quality YKK zips and carry large hook-and-loop panels on the outer face for unit ID or morale patches. The modern cut is shaped for an optimal, low-bulk fit under kit.

Frequently asked questions

What is a combat shirt for?

A combat shirt, or UBACS, is designed to be worn under body armour or a plate carrier. The lightweight torso wicks moisture and cuts heat build-up, while the tougher ripstop shoulders and collar take the abrasion from your kit.

Why short sleeves?

The short-sleeve cut removes the heavy long-sleeve fabric that traps heat, so you stay cooler in warm weather or under armour, without cutting the sleeves off a standard shirt yourself.

What fabric is used?

The sleeves, collar and shoulder area use a sturdy 60% cotton, 40% polyester ripstop for comfort and fast drying, matched to a moisture-wicking knit torso.

Can I add patches?

Yes. The shoulder pockets carry hook-and-loop panels for unit ID or morale patches, and the pockets close with quality YKK zips.

Is there an age restriction?

No. This is a clothing item with no age or UKARA requirement.
