Swiss Link British Army Issued Full MTP UBAC Combat Shirt

The Swiss Link British Army Issued Full MTP UBAC Combat Shirt is a genuine Grade 1 military surplus Under Body Armour Combat Shirt sourced from British Army service stocks. Issued means this is authentic surplus in good used condition: expect minor wear, fading, or service markings consistent with field use. Unlike the standard UBACS, which uses a solid-colored torso panel, this Full MTP variant carries the official Multi-Terrain Pattern across both the sleeves and the main body. Available in Small, Medium, and Large.

Full-Coverage Camouflage Where It Counts

Standard UBACS designs use a plain-colored torso so the shirt can double as a base layer under civilian outerwear. The Full MTP version keeps the official Multi-Terrain Pattern across the entire garment, including the chest and back panels that a standard shirt leaves solid. For anyone wearing the shirt as an outer layer during training, field exercises, or outdoor work where concealment matters, that continuous pattern eliminates the visual break a solid torso creates.

Two-Fabric Construction Built Around Body Armor

The torso is cut from 100% polyester Coolmax mesh, a lightweight, breathable, anti-static fabric engineered to pull moisture away from the skin and reduce heat buildup. This matters most when wearing a plate carrier or vest for extended periods. The sleeves and collar are a 70/30 cotton-polyester ripstop blend, chosen for abrasion resistance against vest edges, shoulder straps, and equipment that would quickly wear through a lighter material. Each zone of the shirt uses the material best suited to the stress it receives.

Pockets and Closure Details

Two angled bellows pockets sit on the upper arms, each secured with hook-and-loop closures. The pocket faces carry large hook-and-loop panels sized for unit flashes, blood-group patches, or other insignia. A quarter-length front zipper with a storm flap allows quick ventilation without fully opening the collar, and a stand collar prevents chafing where armor contacts the neck. Buttoned cuffs adjust for a close fit at the wrist.

Specifications

Who This Is For and Isn't

This shirt suits buyers who need a genuine British Army UBACS in full MTP camouflage for military training, field exercises, bushcraft, overlanding, or collecting, and who are comfortable with Grade 1 surplus condition, meaning light wear and possible service markings are part of the item. It is sized for Small, Medium, and Large only in this listing.

This shirt does not fit buyers who require an unissued or new-condition garment, or who need sizes outside Small, Medium, and Large. Surplus lots are finite and cannot be guaranteed for restock. Buyers wanting a newly manufactured shirt should look for a reproduction instead.

Common Questions

What does "Issued" condition mean for this shirt?

Issued means this British Army UBAC Combat Shirt is genuine military surplus that was fielded and used in service. Grade 1 surplus is in good condition overall, but individual shirts may show minor wear, fading, or markings from military use. The shirt has not been represented as new or unissued.

What makes this a "Full MTP" shirt versus a standard UBACS?

A standard British UBACS uses a solid-colored torso panel so the shirt can serve as a base layer. The Full MTP version carries the official Multi-Terrain Pattern across the entire garment, covering the sleeves, shoulders, chest, and back, and providing continuous camouflage coverage when worn as an outer layer.

What fabrics are used and why does the shirt use two different materials?

The Full MTP UBAC Combat Shirt uses 100% polyester Coolmax mesh on the torso for moisture management and breathability under body armor, and a 70/30 cotton-polyester ripstop blend on the sleeves and collar for abrasion resistance against vest edges and equipment straps. Each zone uses the material best suited to the stress it receives.
