Thanks again Giles. By only colours left in JP, do you mean these are unlikely to make another appearance? Happy to continue holding out, if I know there's a glimmer of opportunity.
I’m XL in most shirts and have L and XL in these. The L’s are snug on me which is what I wanted. In cold weather I wear them under heavy shirts and vests as a base layer. However the XL’s are a good comfy fit and I can layer over a tee shirt if I want to.
