Thanks for your detailed input because I really hate the Uniqlo soft touch material/shirts. I can't imagine wearing a bulky tights like that under some jeans or joggers. I'll stick with the extra warm for now which aren't that thick or thin.
I still have brand new in the manufacturer bags 3 Uniqlo camo flannels I think from 2yrs ago. A dark green, black and navy. Beautiful shirts. Good quality too I found these slightly thicker than the usual Uniqlo flannel they have in tons of colors. Been saving them for a special occasion. I just have so many new stuff I haven't bothered to wear.
