Under Body Armour Combat Shirt (UBACS) PCS MTP

The Personal Clothing System (PCS) is the British individual clothing system, an equivalent of the American multi-layer "ECWCS" system. PCS was created to replace the previous-generation Combat Soldier 95 (CS95) clothing set, introducing a number of improvements:

• Modern materials that maximise body heat retention with less material weight.
• Improved temperature control and its regulation through the use of new materials and technologies.
• Better and more convenient use of the clothing together with body armour
• Faster access through the partial elimination of buttons.
• Better and more compact storage of outer garments using integrated stuff sacks.

More about the PCS system

Infrared Reflective Remission (IRR) is a technology that reduces the user's visual signature so that they blend in with the environment when viewed through night vision cameras. IRR technology works by creating visual interference caused by multi-layer infrared reflections for each colour in the image, which has a specific reflection wavelength in order to blend with colours in the infrared spectrum. As a result, the user's visibility at night is significantly reduced thanks to a reflectivity that imitates the same wavelength as snow, stone, various urban buildings, trees and other green vegetation.

Insect repellent — protection against insects. The fabric of this garment has been treated with permethrin, a substance that repels insects. The treatment is wash-resistant and lasts for 50 machine washes. If you normally wash this garment once a week in a washing machine, the treatment will last 1 year. If you regularly wash the garment by hand, the treatment will last approximately 6 months. The treatment is effective on the clothing, but for full protection insect repellent must also be applied to bare skin.
