I'm selling this because I accidentally bought a duplicate. I've opened the one I'm using, so the item I'm sending is completely unopened. It's made of sturdy quilted material. It's convenient for the gym or short trips. Size: Width 50cm, Height 30cm, Depth 25cm Includes a shoulder strap. The outside is designed to be attached to a carry-on suitcase. There's a zipper at the bottom of the main body for shoes, etc. Inside, there's a zippered pocket and three side pockets with dividers.
