The MMB/MBHOF tee is made from comfortable high-quality 100% cotton. It’s the first shirt we made when we opened in 2015, and our volunteer team wears them while on duty at the museum! Small Marin Museum of Bicycling (MMB) vertical-style logo on the front left side in silver, and the original Mountain Bike Hall of Fame (MBHOF) emblem from the Crested Butte days centered on the back in glorious color.
