Specs and fit

The San Francisco 49ers football jersey, in detail

There's a version of the San Francisco 49ers football jersey you keep for occasions, and this scarlet one you wear on a Tuesday. It's built for the second.

Between a home and an away San Francisco 49ers colourway, most people end up wearing the home one more. It's the shirt that matches the highlights on a Sunday morning and the one you'll reach for without thinking about it. That's usually the deciding factor.

A high-gauge San Francisco 49ers knit with a smooth hand-feel that doesn't cling. Colour-matched thread through every San Francisco 49ers seam, so nothing reads as an afterthought.

Lettering	Custom lettering offered on most San Francisco 49ers sizes

Q01Will a San Francisco 49ers jersey work layered over something else?▾

It will. There's room through the armholes and shoulders of this San Francisco 49ers cut, so it goes over a tee or a hoodie without bunching across the back or pulling at the seam. The body is straight-cut rather than tapered, which is what keeps the shape clean when there's another layer underneath.

Q02How should I wash a San Francisco 49ers jersey so the scarlet lasts?▾

Cold water, inside out, and air dry. That's the whole routine for the San Francisco 49ers jersey, and it takes less effort than most people expect. Heat is what dulls a colour and moves the fibres, so the drying stage matters more than the wash cycle itself. Skip fabric softener too, because it coats the knit and flattens the finish.

Answers before you order

What buyers ask before ordering

▾

What is the San Francisco 49ers jersey made from?▾

A lightweight performance knit with breathable mesh panelling, finished with twin-needle hems and reinforced shoulder seams. It's soft against the skin, structured enough to hold its shape across a season, and colour-matched thread runs through every seam rather than reading as an afterthought.

Is the San Francisco 49ers jersey true to size?▾

It is. Order your normal size for a regular fit, or one up if you want the looser terrace look. The size chart on this page converts a chest measurement directly into a size, which is the number that matters here. If you're between two, take the larger one and you'll wear it more often.

Will this San Francisco 49ers jersey shrink in the wash?▾

Not if you wash cold and air dry it. Heat is what moves the fibres, and it's the combination of a warm wash and a hot dryer that shrinks a jersey, rather than either one on its own. Keep it out of the tumble dryer and it stays the size you ordered.

Which sizes does this come in?▾

This football jersey is offered in Men's / Unisex. The size selector above shows exactly what's currently in stock, and the chart on this page converts a chest measurement straight into a size. If you land between two sizes, take the larger one and you'll wear it more often.

What if the name I want is already on the shirt?▾

Tell us what you're after and we'll confirm the spelling and the layout before anything is applied. If you want a different name to the one shown, that's a custom order and we'll set it up for you. Lettering is the one thing we can't undo once it's pressed on.

Will a San Francisco 49ers jersey keep me cool in a packed stand?▾

That's what the ventilated panelling is for — mesh sits where heat builds up, so air moves through instead of sitting against your back. The knit is mid-weight rather than heavy, so it works on a warm afternoon without going thin and cold once the temperature drops.
