All our cross-training athletes had been asking for a hardcore backpack/duffel transition pack. Well, excuse us for taking so long but we had to put the finishing touches on the mother of all transition packs, and we spared no expense. 1680 denier ballistic nylon from head to toe. Dual straps for backpack use, that remove to transition the backpack to a full use duffel bag. The interior is lined with anti-microbial protection throughout and there's enough room for a few days worth of gear. Custom side pockets for at least 2 pairs of your new sneaks. Tough as heck webbing (we're known for using the good stuff), and of course our custom metal pulls for all those that require perfection. We're proud of this one, we hope you are too!
