Start with what it is made of: breathable athletic mesh with vented side panels, cut so air moves instead of trapping heat.
Construction is straightforward: a breathable mesh body, vented side panels, heat-sealed lettering and a V-neck collar. Cut for men, sized men's S–3XL. It ships with the name and number already applied — nothing to iron or assemble on arrival.
It reads as San Francisco 49ers gear anywhere, but the palette points straight back to Santa Clara, California and Levi's Stadium.
The body is cut a touch longer in back, which is what keeps it put through a standing ovation. The mesh body hangs flat instead of bunching at the waist.
Who This Jersey Is For
This jersey is for San Francisco 49ers fans who want Vapor F.U.S.E. on the back — game day, watch-parties, and everyday team wear for men.
Washing & Care
Machine wash cold inside out with a mild detergent, then tumble dry low. Skip fabric softener and high heat, and do not iron directly over the lettering.
