I have a 3 yr old pair of the MT500 shorts(XL). In one word-AWESOME! I'm a fit, 5'10", 192lbs 60 year old who can still keep up. I wanted bibs, so I went for the MT500s as soon as I saw a discount online. I ordered the XL & am, once again, very pleased with Endura's high quality product. The fit is very good, however I now think a LG would have fit me as well. So if you like them smooth & tight all over, order according to your true size.The material has changed a bit & time will tell if they are as tough as the originals. I'm betting they are. After 4 long rides the fit & feel is great. The chamois is soft & has broken in nicely. A great product to spend your hard earned cash on!
