A saddlebag or seat bag is a bag attached under the saddle or seat. Smaller bags are typically used to hold a few items such as spare inner tubes, puncture repair kit, tools, rain gear, food, first-aid kit, etc. Seat bags are common on touring bicycles, racing bicycles, and cross country mountain bikes. Bags range from tiny to large (over 25 liters). Smaller bags, known as seat bags, wedge packs, or seat packs fit completely under the saddle. Larger bags which project behind and sideways are usually called saddlebags; a well-known example is the Carradice Long Flap, for many years a staple of British cycle tourists especially on the weekends.
