Canyons involve a lot of sliding, scraping and general thrashing. Which ends up with a lot of scraping and thrashing of the gear and clothing upon which that sliding is done. The harness, the shorts, the wetsuit - they all get destroyed on a regular basis.
While the ScuttleButt is for the scrapiest canyons, the NEW Shuffle Butt is a lighter, more flexible version of the same for non-scrapey canyons. Perfect for Zion, Death Valley, etc. Lighter on the butt, so to speak. Less durable, certainly.
How Long will it Last? Hard to say. Depends. The seat is made of a 1000 denier coated air-textured nylon fabric and should be pretty good. My experience is that it will last a while, and can be repaired or patched. I don't see duct tape working on these, but AquaSeal can be used to glue patches on.
