Okay, have read some reviews from people not happy with sizing. "...way too small". "...far too tight". Sure, no one wants the circulation down there turned off, but these undershorts are supposed to be snug! Too baggy and the shorts will rub. I have found that although they were tightish out of the bag, after one ride they had moulded to my body shape and now feel like a second skin. As always Endura have produced a well considered and very well made bit of essential kit. Yes they are expensive but bare in mind this bit of kit will last for years. Have tested on 6hr cross country rides. Padding just right and very comfortable. Perfect when combined with Endura Singletrack trousers.
