I have the HSS and I like it alot, but the seat belt buckels are a bit bulky. Anyway, I took mySkyline-Horizon winter coat to a taylor and had a slit cut and sewn for the teather strap to pass through, so I can keep my coat sealed tight. It really works great but I think quality garments should come with this.
The teather strap comes right off the top of the harness unlike what someone said earlier.
