San Francisco 49ers colours have looked roughly like this for decades. This alternate jersey keeps that line intact with Fred Warner Vapor F.U.S.E. Stitched named on the back.
Cut sits between slim and boxy, so it layers without looking oversized. The mesh body hangs flat instead of bunching at the waist.
This is the alternate build rather than match-worn kit: the same San Francisco 49ers look, a fan-weight mesh body, and a cut that layers over a tee. Sizes run men's S–3XL on the US scale. Sizing follows the US scale, so the letter size you normally wear is the right call.
It reads as San Francisco 49ers gear anywhere, but the palette points straight back to Santa Clara, California and Levi's Stadium.
