I have been cycling for about 40 yrs. I've worn everything from PI to Capo to Castelli...and the list goes on. I never considered Assos because of the price. About 5 yrs ago I saw a killer deal on Assos bibs so I bought a pair. It was eye opening. For the first time kit fit me. Albeit like body paint. Now all my kit is Assos. Bibs, gloves, jerseys, socks....etc. My experience is that Assos fits smaller and lasts forever. I still have everything I ever bought and wear it whenever I ride. Expl on size. My chest measures at 43". For most clothing that's a L or XL. I wouldn't be able to get into a L in Assos. And, XL is race fit for me.
