TETHRD SYS HAULER ES V2 COYOTE The 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. 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. However, there’s no wrong way to do it. Since each SYS Hauler is modular and extremely light weight, you can use them to fit your needs.
