Is this the best bag we've ever made? We definitely think so. The Ground Control ROLL TOP backpack has something for everything, and is built to take a beating. Featuring a front panel that securely holds skates; zipped-up - this compartment doubles as shoe & sweaty stuff pocket; keeping your dirty items separated from the main, internal section. It can also be used to carry oversized items like a yoga mat or tripod. Look at that OG GC logo! The roll top is expandable and the volume can be increased by up to 1.2 gallons (3 liters). A compartment at the bottom of the bag with 2 media ports is a great place for a power bank or eSkate battery. Other useful features include a padded laptop sleeve, multi-purpose mesh side pocket, airpod/mouse zip-pocket, large side zip-pocket, a hidden air tag sleeve and a secret stash area in the double bottom that is big enough to hold a passport, credit cards, money, keys, etc. When your fully packed up, skates and all, you can easily access the main section of the pack with a convenient side-zip. You'll also enjoy the bottle-opener zipper head at the end of a long skate. Everything you need held securely within classic GC detailing.
