Bring a little, or a lot.
You can pack this one to brim before you head out for the weekend without having to carry it back sagging and half-empty on the return trip. The Sonoma Seat Pack from Timbuk2 uses a long roll top closure that lets you stow an impressive 11 liters of cargo or just roll it down for a more compact load. It uses a straightforward strap attachment system to the seatpost and saddle rails for a universal fit, and an external zippered pocket makes it easy to access your keys or wallet.
Features reflective striping for enhanced rear visibility.
11 L max capacity. Made from lightweight ripstop nylon. 381 g approximate weight.
