Revelate Designs Terrapin System Seat Bag 8 Litre

The Terrapin® 8L is a smaller version of the modular Terrapin® System. Like the popular Terrapin System, the mount stays on the bike and the custom fitted air purge drybag is removable for easy packing.
With 8 litres 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.

Recently updated, the new features include a bungee loop on the top of the holster so you can quickly lash down that extra layer and a new rear strap design. The updated drybag features hypalon slots for a rear light attachment, a low profile one way purge valve.
