Very practical, since it has enough space even for travel. It seems to be of quite good quality construction. For the gym, it is just what you need if you throw bulky equipment inside. It easily fits gloves, wraps, towel, shin guards, a large water bottle, and a change of clothes. It has three external pockets. In both the Skroutz and Leone descriptions, it says it is made of nylon. However, inside there is a label that says 100% polyester. Nevertheless, it has quality zippers, straight seams, it hasn’t lost any color either in washing or in use, with considerable use it hasn’t worn out and so far I haven’t found any flaw. In the photos on Leone’s site, the fabric does not look like nylon. Since it arrived well packaged and with all its tags, I believe they simply changed OEM and/or material and forgot to update their page.
