The Terrapin seat bag system from Revelate Designs is the go to seat pack for travelling cyclists wanting a holster/dry-bag system for taking off the bike when not riding… Like the full bags, the dry bag can be loaded anywhere between 8 and 14 litres, meaning it can be used for anything from a lightweight tour, to carrying as much as you need for a full on bike camping trip. The webbing on top also allows straps to tie extras to the topside of the pack…
Sizes: 14L / 8L
NOTE.
The 14L Terrapin is a large-ish seat bag. Check tyre clearance with bag properly packed and loaded prior to use, to prevent bag damage or worse.
Minimum of 24cm clearance from saddle rails to top of tyre
Minimum length of exposed seat post is 12.5cm
