We reviewed dozens of gym bags and our favorite is currently on sale.
Arbor 30L Duffel
This is the *perfect* gym bag. You can fit everything you need in this bag for the gym. The best part is that it's included in Patagonias annual sale. Normally $79, you can pick one of these up for as low as $55. If you're in the market for a new gym bag, give this a try. We strongly recommend.
