It looks like linen as it is a linen and viscose mix. I'm very pleased with it, I don't like pure linen as it creases so easily but linen mix still has the look but not the bad creasing. It doesn't show in my picture but there is top stitching along the seams and pockets. I must try and get a better picture of that detail. Also, there are button tabs at the ends of the sleeves - a nice touch that I thought. I got it from the shop that a lot of women scorn, Edinburgh Woollen Mill. I've got some nice things from this shop so I really don't understand their aversion, maybe it's because I'm not a posh person like they are!
