I actually just purchased two within the last three weeks. The first harness was a HSS Ultra Lite X-treme Harness. I was in between sizes (S/M,L/XL), so I went with a S/M...mistake, it was too small to wear with layered clothing.
Tonight, I get the second harness which is a Lone Wolf Alpha Tech. While the fit is good, I'm not sure I like some of the LW features verses the HSS. Also, I think the prussic knot will take some getting used to as the knot is fairly tight against the carabiner.
So for now, I'm not sure which harness will be my favorite... might look at the HSS Ultra Lite
