I have done a lot of research into creating the shape and style of these tops to be inclusive and practical for roller derby. We have taken into account a lot of feedback we have had about how derby tops fit or do not fit and tried to create some better options. Each of our 3 fits come in both vest and t-shirt styles and are available in 4 lengths. We have created our own sizing which means these are different from standard sized tops so please read the fitting guide or email us about size samples before ordering.
