I got this bag for my 9 y.o. to carry her skates and "things" to the ice-arena and it does the job and even more because it has plenty of room. I think it is actually sized for an adult because the shoulder strap is quite long but it can be shorten for a smaller body. The two back compartments are for the skates and the front one is for gloves, hat, snack, etc... Adult skates (ice-skates or roller-blades) would easily fit.

Granddaughters loved bag for ice skates

This Proguard figure skate bag is well-constructed and spacious. It has three pockets--two are the same size and the third outer pocket is slightly smaller.

The shoulder strap is generously wide for comfort. The metal hardware is tough and attaches diagonally across the bag. The other end of the strap is sewn directly into the bag, which helps keeps the bag from swiveling around.

This bag is BIG! There's plenty of space. One skate goes in each of the two same-sized pockets, then I put in my wrist guards, large knee pads, a microfiber cloth, soakers, blade guards, snacks, long sleeve fleece, wallet, and water bottle, and there's still extra room. I could fit a change of clothes, street shoes, and a helmet if needed.

There are no grommet holes underneath, but it's not necessary especially in my dry Southern California climate. I simply wipe and dry the outside of my boots and blades completely with my microfiber cloth, put soakers on my blades, stick a paper towel into each skate to absorb any odors. I simply unzip my bag in my car or when I get home to evaporate any ambient moisture from my cloth.

UPDATE ON 9/9/20:
I just figured out that my inline skates fit in the bag.

Really nice bag- durable and love the size!

My 9 year old daughter can fit her size 4 skates, change of clothes, and extra shoes when needed. She absolutely loves it!
