Well, if the Doyeah 0858 80 denier tights came as a pleasant surprise, the 0838 10 denier ultrasheer STW tights are simply awesome! The fabric is really silky and fairly shiny, and in the skin-tone colour they are really stealthy (unless the reflected light gives them away!). Although the makers quote the same size range for the 'one size' sizing as the 80 denier style, I would say they will not suit much bigger guys than me (6ft tall, 36" waist, 32" inside leg) as they are approaching the upper end of the range on me; whereas the 0858's seemed to have loads of room left, these don't. They have a very similar male centre panel, with flat seams and fly opening, to the Gerbe men's tights, although these are, of course, sheer to waist, whereas the Gerbe's are not. There is a reinforced area around the seams (just visible in the photo) and the toes have a near-invisible reinforcement. They are extremely comfortable, and appear to be reasonably durable (a little early to tell yet, I know) and certainly don't appear to be overly fragile (having said that, it is a good idea to handle them with hosiery gloves, as I did; they are only 10 denier, after all!). Another surprise find, and especially so at the bargain price!
After having lived with the Doyeah's for a while now, I can report that they have undergone a fair few wash/wear cycles with no ill effects that I can detect - they seem as good as new! This is a pleasant surprise - it is unusual for ultrasheers to last this well!
