A workhorse combat shirt for under your armour

The Kombat UK Spec-Ops UBACS is built for players who run a plate carrier or chest rig. The elasticated ultra-flex torso hugs the body and moves with you, while the fabric wicks moisture and dries fast, so you stay cool and comfortable under layers of kit.

Tough where it counts

The sleeves, shoulders and collar are made from hard-wearing 65% cotton, 35% polyester ripstop, placed exactly where a combat shirt takes the most abrasion. A quarter zip at the neck lets you dump heat quickly, and the elasticated cuffs keep the sleeves in place.

Protection and practicality

Removable armour elbow pads slot into the sleeves for extra protection during low crawls and hard cover grabs. Angled utility arm pockets give fast access to notepads and field aides, and hook and loop panels let you run your own morale and ID patches.

Kit it out at Platoon Stores

The Spec-Ops UBACS is a smart-value base layer for any loadout. Pair it with a plate carrier or belt rig from our tactical gear range for a complete setup.

Frequently asked questions

What is a UBACS shirt?

UBACS stands for Under Body Armour Combat Shirt. The stretchy, breathable torso is designed to sit under a plate carrier or chest rig, while the tougher ripstop sleeves take the abrasion on the outside.

Do the elbow pads come with the shirt?

Yes. The Spec-Ops UBACS includes removable armour elbow pads that slot into the sleeve pockets, so you can add or remove them to suit the game.

Is it good for summer airsoft?

The elasticated torso fabric is lightweight, fast-drying and moisture-wicking, which makes it well suited to warm-weather skirmishes and layering in colder months.

Will patches stick to the arms?

Yes. Each sleeve has hook and loop ID panels for morale patches, flags and ID markers.

How should I size it?

The shirt has a snug, athletic UBACS cut. If you plan to wear heavy layers underneath, consider sizing up. Refer to the Kombat UK size chart for chest measurements.
