They are comfy, come out the box and feel amazing... winner right? I have their briefs, a lot of them. \n\nNotice they do a three month subscription at a discounted price, there's a reason. They are absolute shite quality. \n\nOn almost every pair the elastic has come out, started to thin and just generally looked scruffy after washing them.  Now I gave them the benefit of the doubt that id maybe been washing them too hot, so ordered more (because they're comfy and look good) and washed them separately because they are expensive... same thing happened. Then on so many pairs the same thing happened again and again, the material went thin, easily had small holes in them and on either side where the front and back meet, split and stitching came undone. I did complain and they sent me 6 pairs for free which I thought was pretty cool but again the same problems.  Their lifespan is about 3-4 months, possibly they know this hence the subscription idea?  Complained again and got a 30% off code that im yet to use, fed up of the poor quality.
