Jupiter Duffel
One hook by the door, two bags: a leather gym duffel bag for Tuesday night and something more respectable for the coast run on Saturday. The Jupiter is meant to be both. Full-grain leather with our engraved weave pattern, structured enough to sit on a locker room floor and clean enough to carry through a hotel lobby.
The 20 in. size takes a gym kit and shoes, or two days of clothes, which makes it an overnight bag as much as a training one. The 24 in. handles a proper multi-day trip. Both come with the shoulder strap, because a loaded duffel carried in one hand gets old within about a block.
The 20 in. sits inside most airline cabin allowances, so it doubles as a weekend bag without an argument at the gate. Here is what it will not do: there is no padded laptop sleeve in a leather gym duffel bag built this way, and we would not put a work machine in loose alongside gym shoes. For that half of a trip, the Atlas Backpack is the better other half. If you are weighing sizes rather than styles, our duffel size guide works through them against real trips.
Care is simple: a dry cloth for dust, conditioner every few months. Our leather care checklist has the full routine.
Which size do most people buy?
The 20" if the gym is the main use and you want it to pass as carry-on. The 24" if you are packing for three or four days.
