Review on Chase Harper USA 4250 Deluxe Hide-Away Tail Trunk - Water-Resistant, 🔵 Tear-Resistant, Premium Ballistic Nylon - Universal Fit Bungee Mount System - Blue by Brandon Hayes

I use this as a back seat bag on my Ninja 750. When folded it fits the width of the seat perfectly and when unfolded it fits the width of my MadDog saddlebags perfectly. It comes in an incredibly small package and you need to unzip it and expand it to its full size, so don't be disappointed when you open the package for the first time. That's a great bag.
