The British MTP UBACS combat shirt is a genuine garment from our UK military surplus range, designed to be worn beneath body armor while helping the wearer remain cool and comfortable.
UBACS stands for Under Body Armour Combat Shirt. These shirts were developed to reduce unnecessary bulk and improve comfort when worn beneath body armour, tactical equipment or load-carrying systems.
Unlike the more familiar UBACS design with a plain-colored torso, this version features British Multi Terrain Pattern camouflage across the full body and sleeves. Its Coolmax construction helps manage heat and moisture during physically demanding activities, making it a practical choice for warmer conditions or active outdoor use.
The shirt can be worn beneath tactical equipment or used independently as a lightweight field shirt. It is particularly well suited to airsoft, paintball, bushcraft, hunting and other activities where freedom of movement and moisture management are important.
As a former Royal Marines Commando, I appreciate the practical thinking behind combat shirts: reduce unnecessary layers, maintain freedom of movement and manage heat where equipment sits against the body. This full-bodied version also provides a more consistent MTP appearance when worn without armour.
