Maybe not Leo at Bezos' wedding incognito mode, but a socially acceptable introvert's incognito mode. Material: Cotton twill Fit: Unstructured, mid-profile. Interior taping gives a comfortable fit with embroidered eyelets for enhanced breathability Adjustability: Closes with an adjustable self-fabric strap with metal slider Bolt logo is embroidered on the front The contrast Swoosh logo is embroidered on the left-side middle panel Made of at least 75% recycled content and/or organic content Please note: Although this cap is noted as M/L on the label and on the ordering grid, it is only offered in one size.
