The Helikon-Tex MCDU Combat Shirt is a long-sleeve combat shirt designed for operators and shooters working in hot conditions, with or without overlaid ballistic equipment. The cut works in synergy with plate carriers, chest rigs and tactical vests through a close torso silhouette and structured sleeves.
The shirt body uses a 100% TopCool polyester insert in the highest heat-buildup zones: the technical fabric promotes moisture evacuation to the outer surface and dries quickly after intense exertion. The sleeves and mandarin collar are instead made from NyCo Ripstop 50% cotton / 50% nylon, more resistant to the abrasion and mechanical wear produced by load-bearing shoulder straps and protective gear. This material combination resolves a real-world trade-off: the torso gains maximum breathability where heat generation is highest, while the sleeves retain the durability needed to withstand daily friction from equipment without breaking down.
The two zippered bicep pockets allow quick access to small items such as folded maps, documents or navigation tools, without interfering with arm movement. The two loop panels on the shoulders allow identification patches or national flags to be applied securely and removed without leaving marks. The PenCott WildWood camouflage is developed for woodland environments and temperate vegetation, with a colour scheme that breaks up the silhouette against mixed backgrounds of green, brown and grey.
Key points
- The TopCool body wicks sweat rapidly, keeping body temperature in check even with overlaid equipment.
- The NyCo Ripstop sleeves withstand continuous abrasion from shoulder straps and protective edge contact without deteriorating over time.
- The zippered bicep pockets stay closed during movement but remain one-hand accessible without removing any gear.
- The loop panels on the shoulders allow quick customisation with IFF or identification patches, no additional stitching required.
- PenCott WildWood camouflage is calibrated for woodland and mixed temperate vegetation environments.
- Available in seven sizes from XS to XXL, with chest circumference from 86 cm to over 116 cm and sleeve length from 67 cm.
