Mesabi Large Bike Seatpost Bag

Mesabi Large Seatpost Bag – Designed to carry all of the gear you need to Bikepack and Tour across the globe or across town! Securely attaches to your seatpost and your saddle to evenly distribute and balance the pack weight for better riding stability.  Mesabi Large Seatpost Bag weighs only 21oz and attaches directly to your bike, eliminating the need for heavy and expensive metal racks.

Waterproof Material and Construction – Constructed from durable and Waterproof TPU-Laminated Ripstop Nylon material with sealed seams, Mesabi Large Seatpost Bag has a single roll closure opening.  Stuff in your soft gear (sleeping bag, clothes, etc.) then roll close the opening and secure and tighten buckles. Great pack for carrying your sleeping bag/pad or clothes. Maximum weight capacity 10 pounds!  Volume 8 – 16.5L. Recommend to roll close the pack opening at least 3 – 4 times for waterproof seal.

External Attachment Points – External series of loops can be used to attach rear riding light or other small light gear.  There are also elastic cords for loosely securing other gear (towel, light jacket, extra clothing, etc.).

Secure 3-Point Attachment to Your Bike – Velcro and buckle system attaches to 3-points on your bike (2 points on the seat post and at the back of the saddle).  Internal PE Frame stiffens the bag in order to hold the shape and prevent excess movement and tire rub.

Near Universal Fit! – Fits any mountain, road, fat bike, or touring bike with at least 6 inches of seatpost exposed and at least 7 inches of clearance from the back of the saddle to the rear tire.  Compatible with carbon seat posts. Not compatible with dropper seatposts.
