Sportswear vs Sportsgear

What is the difference in usage of those two words? For what I know, they both mean the same and somehow I couldn't find a dictionary entry for the word Sportsgear.

Sportsgear and seen in this site, is selling sports clothing. And sportswear pretty much means the same.

So, when and why in a few example scenarios would I use each particular word?

The website provides an answer.

When clicking on gear, it shows socks, hats, watches, and backpacks.

When clicking on sportswear, it shows pants, shirts, shorts, socks, and other items of clothing.

Gear is equipment used for a purpose. Xwear (winter wear, sportswear, swimwear, etc) are items of clothing worn. Some may disagree but I don't feel "gear" can be used to talk about pants, or underwear.
