Topo Designs takes the large cylindrical bag and shrinks it down to size making it more manageable to carry on the go. The new Mini Duffel Bag is great for carrying all your gym gear for an after work exercise session, or maybe even your smallest day-to-day gadgets. Constructed in 1000d Cordura, the bag might be small but it’s built tough to handle anything. Available in four colors, the bags are available now on the Topo Designs website for $69.
