Revelate Designs Terrapin 8-Liter Seat Bag

The Terrapin® 8L is the smaller version our flagship Terrapin® System 14L. The Terrapin 8L maintains all of the Terrapin's best known features including a mount that stays on the bike with a custom fitted drybag for easy packing. With 8 liters of capacity, it is perfect for most lightweight bikepacking trips and fits bikes with low tire clearance. It is perfectly sized for small framed bikes, including plus bikes with inherently diminished clearance.

The Indie-Rail attachment system is a progression from conventional bikepacking bag mounts where the rail straps are fixed to the top center of the bag. 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. We combine this with rigid internal structure and active camming buckles to prevent straps from slipping on rough terrain.

The mount is stiffened on all sides including an external plastic bottom sheet which protects the bottom of the bag like a fender. A composite internal top sheet provides a solid and stable platform for the strap points and transmits the vertical load to the seatpost connection.
