Where tight trails and rugged terrain would batter other bags, the EXP Series Saguaro Seat Bag shines. It connects to saddle rails at four points for supreme stability (say goodbye to sway). Its modular dry bag holster design makes loading and unloading a cinch and ensures your gear stays as dry as when you packed it. A purge valve lets air out, but not in, so you can compress the bag to pack more. The holster fits either our Medium (9 liters) or Large (14 liters) dry bag to adapt to different adventures. Saguaro also plays well with dropper posts, so you can send steep and techy lines without sending your bag straight into your tire. Fill Saguaro with your gear and go seek out wild routes.
