Evoc Seat Pack Ultra Waterproof Black, 4L

What Our Gearhead(R) Experts Are Saying:"I ran the Seat Pack Ultra Waterproof on a two-day bikepacking push and never once felt it shifting under me. The roll top closure kept my sleeping layers bone dry through a surprise downpour, and the seatpost stabilizer meant I could stand and sprint without the bag swaying into my legs."The climb tops out, the gravel turns to singletrack, and your seat bag hasn't moved an inch. That's the kind of trust the Seat Pack Ultra Waterproof earns, a saddle bag built for riders who want to go far without hauling a full pannier setup. Strip the bike down to essentials, and this pack becomes the difference between a clunky ride and a fast, focused one. The roll-top closure flexes to whatever you're carrying, and the elastic cords up top give you a spot to lash a layer when the weather turns.
