I am not a great runner but I have been running for 30+ years. 17 marathons including 3 Boston’s so comfort, fit, and material are all part of an ongoing search for the perfect shorts. In these I feel like I have found the holy grail of shorts. 2-1 minimizes chaff better than compression shorts as a separate and the material with quick dry and little weight deals very well with hot long runs. One marathon wearing them and bought a second pair - mostly because the orange is a statement although not sure of what.
