This British Army surplus thermal fleece undershirt is issued as part of the current PCS clothing system and is the replacement for the ever-popular Norwegian shirt.

The long-sleeved PCS combat undershirt is made from 100% polyester that is lightweight, quick-drying and has improved thermal insulation.

The shirt has a zipped neck with top cover to prevent the zip from rubbing against your neck.

Thumbholes in the cuffs prevent the sleeves from riding up especially when adding or removing clothing layers and they also provide some added warmth to the lower hands.

A lower length back on the shirt gives added warmth and protection to the seat as well as preventing the shirt from becoming untucked.

The PCS thermal undershirt is ideal for winter and extreme cold conditions. It is also ideal for wearing under a waterproof outer layer or over a t-shirt in warmer conditions.

Please note: These items are used Grade 1 surplus that have previously been worn, with all functioning items working such as zips, buttons and Velcro. No holes, rips or repairs. Might have writing or badges on the item.

So warm even at freezing temperatures.

Love it

This is my second purchase from military kit site. I bought the thermal fleece with least expectations. But I am so happy I bought it. Super comfy, classy design and excellent warmth. The only point I felt a bit was the arms were a bit tight when I used the hole for the thumb. I will definitely buy again to gift others now. 100% worth it.

Robet Davis (London, GB)
British Army PCS Thermal Fleece Undershirt

This is a great piece of clothing and promises to be very warm during the winter. A point to note, the dropped back is long, I'm 5' 10" and it reaches to the top of my thighs. Fit seems about right. I purchased an XL and it's baggy on me (41 inch chest) which is what I wanted.
