The Viscacha™ (vis-KA-cha) does it all. Take it on the Great Divide Route, the Iditarod trail, or long day trips.
The roll down opening allows the bag to easily expand or compress in volume. A removable internal compression strap aids in packing and closure, dual seat post gripper wrap attachments give a super stable attachment. High density foam stiffens up the seat post connection and a flexable plastic bottom sheet adds support along the bags length.
Beefy where it needs to be, lightweight where it does not.
Carbon seatpost friendly
You need a minimum of 8" clearance from saddle rails to top of tire.
Minimum length of exposed seat post is 5"
Note: If you run your saddle all the way foreword on the rails the bag will rise above the saddle in the back due to the sharper angle between the seat post and saddle attachment.
