SYS Hauler ES 2.0The SYS Hauler system is the OG ultralight saddle hunting storage system. With our simple, 1 handed quick connect method, your SYS Hauler can ride comfortably on your saddle for every hunt, or get left in the truck when you need to be light and fast. There's no limit to what you can store with your SYS Haulers. We like to run our tether and lineman belt on our left hip, and necessary accessories (like the Recliner or HYS Strap) on our right hips.
