What is a sling bag anyway? Just what it sounds like. It slings over your shoulder, often sporting just one shoulder strap, and acts like a backpack or gym bag. With the crazy schedule you keep, when you’re ready to hit the gym, you want to be able to grab and go. Having your gear organized and stored in your sling bag means it’s ready to go when you are. My Sporty Girl has sling bags that have plenty of room to contain your workout clothes, grip bag, valuables, and more. And of course, with cool logos, these bags will also give your gymnast the opportunity to boast about her sport. Large enough to contain it all, and compact enough to store out of the way, a sling bag is your ready companion.
