Wet bike seats are a common problem for bikers during rainy and snowy seasons. However, the “Sub-seat Bike Bag” by Sam Holmes is an under-the-seat bag with a pull-out seat cover that ensures a dry seat for the bikers in all seasons. The seat bag stores a dry seat cover that comes out of the pocket under the seat, so you could ride the bicycle with ease even when you forget to cover the seat during rain or snowfall. Featuring a hard plastic top and a fabric bottom, ensuring comfort as well as durability, the seat cover mounts onto the seat rails with a screw located inside the bag, which opens with a key to avoid theft. While a tail light on the back makes a logical combination with the seat bag.
