The 14L Terrapin® System is a modular, waterproof seat pack with a removable drybag allowing for easy off the bike packing. Approaching nearly a decade since it's first design, this generation of Terrapin has improvements on the stability, ease of use, and durability of the bag.

Sharing features with our award-winning 8L Terrapin System, the 14L Terrapin System features Revelate's exclusive Indie-Rail attachment system. 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. This feature virtually eliminates side to side bag sway without the need for external hardware. This is combined with a rigid internal structure and active cam buckles to prevent straps from slipping on rough terrain.

The Terrapin features an external plastic bottom sheet which acts as a fender to protect the bottom of the bag from kicked up debris. Stiffened on all sides, a composite internal top sheet provides a solid and stable platform for the strap points and transmits the vertical load to the seatpost connection. An external webbing and loop system houses a bungee and provides additional easy access external storage.
