On the topic of shirt sizes and BTWD, can I add that as a bigger guy, 6’1″, long in the torso, and well, let’s just say sporting a hefty weight despite 5 yrs of 3,000+ miles cycling annually, I am always disappointed that the sizes only run up to adult XL. I take a shirt anyway, but they generally see service for me as undershirts, if anything. They mostly just languish in my dresser. I wish they would at least offer a 2X, or even better a 3X for a looser fit. I’d even be willing to pay the couple dollars difference t-shirt manufacturers seem to charge for larger sizes in order to have a shirt I actually could wear regularly and show my support for the event and bike commuting. Food for thought for the powers that be…
