These bags measure 23" L x 12.5" W x 10.25" H so they have plenty of space for a change of outfit and gym shoes.
Brad's Deals Editor Michael,
These Puma Axium Duffel Bags drop from $50 to $20 during the Private Sale at Puma. Plus, the shipping is free, which makes this the lowest price we could find for one of these bags by $20. These bags have two side pockets, an adjustable shoulder strap, and are avaible in the four pictured colors. More colors can be found here, but not every bag from that listing is on sale. Sales tax is charged in most states.
