You DON'T need a new sport-specific bag. Your regular backpack works fine.

I play in a ladies tennis group and have a pile of great condition backpacks that I've accumulated over the years. A lot of the women have nice $100-$250 tennis bags. I especially like the cute "bougie" ones with a racquet shaped cutout.

I only play a couple times a month and use my hiking sling bag to carry my stuff in. Nobody cares what kind of bag you have and if they do they suck!

****struggling to not judge myself or others based on a silly bag.
