A stop at the gym on a workday should be an easy shift. A duffel like this ensures that it will be. Two external vented pockets for items like a towel or extra layer lead the way, while a large water bottle pocket and a laptop sleeve help keep your essentials snug. The bag also offers an external shoe tote and a roll-top design for your gym clothes post-workout to separate them from items you’ll need when you return to the office.
