They are very good - I have never invested in this type of clothing and have been using them all the time since I bought them for running, hiking and general outdoor activities. I like the size for me (US M) which I find comfortable for my 30 inch waist. Can't comment on durability yet, but so far they're holding up well. The reduction by one star is for quality control in sizing and although they are well stitched (good seam placement, NO center back seams) waist measurement can vary by up to half an inch and the material does vary from pair to pair pair up (maybe fabric color slightly different?) - some are thinner, thicker - actually pretty funny that some fit tighter or looser than others - it's not a deal breaker but I did notice a discrepancy between the 9 I bought.
