So the price / performance ratio is great, one not so good quality of the substance had expected for the price. If necessary, I'll probably order again there. Addendum: So after 2 washes came the disillusionment. The T-shirt is still in shape and color, but the fabric attracts dust like a magnet, so I look like a lint roller and it is no longer acceptable for me, more than in the garden for lawn mowing, so there is of me instead of the current 5 star only a star. A wash error I exclude also because I use no fabric softener, even a dryer. The T-shirt has been washed at 30 degrees. My Deo immortalized with white stripes on the shirt, which does not make it with other substances. Too bad now no longer the price / performance ratio naturally :-(
