My brother and I were having this debate. Thinking of picking one up to wear in an upcoming HM race. it looks like a high quality top that is light and breezy. In other sports its normal to wear the team jersey as a fan, but what about in running? For context neither of us are very fast, both aiming for sub 90 HM (F25, M21). I guess we could buy another colour, but the blue and green one does look great imo.
