Perfect for lightweight bikepacking trips on bikes with low tire clearance, the updated 8-liter Revelate Designs Terrapin System seat pack combines a mount and dry bag for modular waterproof storage.


  • Indie-Rail attachment system tightly cinches down to each saddle rail to eliminate side-to-side bag sway, providing a stable mount without any extra hardware
  • Dry bag features RF-welded waterproof construction to keep your gear dry; 1-way air purge valve rids bag of excess air while maintaining a low profile inside the bag
  • Dry bag not intended for prolonged submersion
  • X-Pac fabric panels are twice as abrasion resistant as standard VX material, increasing the mount's durability
  • External webbing and bungee offer additional easy-access storage
  • Composite internal topsheet provides a solid and stable platform for the strap points and transmits the vertical load to the seatpost connection
  • Mount is stiffened on all sides and includes an external plastic bottom framesheet that protects the bottom of the bag like a fender
  • System is compatible with carbon seatposts
  • Terrapin mount weighs 369 g (13 oz.); dry bag weighs 113 g (4 oz.)
  • Note: It's important to check tire clearance prior to use, as contact with your tire can cause a wreck; Revelate specifies 7 in. minimum tire clearance from saddle rails
