From the Iowa Hawkeyes’ site where you purchase their official gear. It took me a while to figure out where to click in order to get a man’s sweatshirt.
That’s because “Apparel” is what you click for men’s clothes. If you need women’s, it’s got its own tab. Women are interlopers into sports and therefore they don’t normally purchase sporting clothes. It makes it seem like “Womens” was added on later, as an after-effect. The “normal” Hawkeye’s fan, the ones who deserve a gender-neutral tab are the menz.
It’s one of those subtle ways that misogyny is reinforced: men loves sports, women do not unless it’s an anomaly.
UPDATE: Sociological Images has a ton of examples of this phenomenon where “men” = neutral.
