Modeled after a vintage 1960s Italian seat roll, this holder is manufactured by Yanco, a Los Angeles-based bag maker that sews everything by hand. Built from 10.1-ounce Martexin waxed duck canvas, each roll fits multiple CO2 canisters, a spare road tube, tire levers, credit cards, and keys.
The best part: It fits snugly under your saddle, not seatpost strap required.
