I just found these kevlar under wear in grey - and I am saving up for them: expensive but ideal for under other clothes. Much nicer than the original yellow stuff. My thinking is that I go through my normal jeans in about six months of work and play and prefer to buy cheap ones and cargos, i.e. <$30 a pair so with these under them I can chop and change the leg gear. Don't know about the shirt as I wear my leather jacket all year but I shall see how the legs feel and maybe get one for next summer.

I have also found a range of kevlar lined hoodies, long Ts, gloves etc. at http://www.bladerunner.tv/mens-hoode...ea2km3bmuvq9n0
however although Kevlar lined and properly rated as stab proof it may not be suitable for abrasion. Cool gear though ...
