UK issue PCS Thermal Smock Sizing ?

[Scots_Charles_River]

Hi, what sort of sizing is this ?
For example on top of a thin fleece, what is a loose freedom of movement size ?

Thanks

New army sizing is terrible seems to have changed from the dpm days. Always go 1 size up.
The top you show has a reputation of sticking to other clothing because of its own inner fleece, especially another fleece.

I thought that those new tops were meant to go on as the second layer, over the base layer and were supposed to be like a Buffalo shirt?
That's how I wear my cool weather jacket; over the lightest and thinnest Patagonia base layer; almost but not quite bare skin, then the high loft shelled jackets or the poly-cotton smocks over that.

Go one size up, the arms are annoyingly short on them.

Medium or large doesn't fit me...avoid
