I have no experience with the Rescue harness, but I do own a HSS Pro series. I LOVE it! I often don't even tell I have it on. The added pockets are nice for calls, gloves, snacks, etc. You won't be disappointed with an HSS. Good luck with whatever you choose!

that was the one i was also looking at, my rescue one came today but haven't had the chance to open the package.

Its does have some weight to it, assume from the steel buckles and rope. Ill come back with more info after I try it.
