Very handy to keep your rain or wind jacket, all the food, spares and repair stuff. Padded construction adjacent to top and down tubes allows you to carry electronics and a camera as well. It is securely attached to your top tube and other tubes of your frame and holds its shape well.
Twin compartments accessible with waterproof zippers, spacious at the main while you may put documents, valuables, etc. at the smaller compartment. Get organised with inner mesh pockets.
Hidden exit at the front for charging cables and water bladders. Zips are covered for extra resistance to pouring water.
