Revelate Designs Terrapin Seat Bag

The Terrapin System is a holster-like mount with integrated RF welded drybag. The load can be quickly removed from the bike for packing/unpacking. With Indie-Rail, each saddle rail is cinched down hard to the sides of the bag, virtually eliminating side to side bag sway without the need for external hardware.
