The focus has great padding and support, that provides good comfort during falls and while belaying.
There are definately lighter harnesses out there.

Went for the Momentum AL Package, which is nice, but bought the Focus AL and made my own package for not much more money. It is a great harness of excellent quality. Very, very, very comfortable. Works flawlessly and is a great deal for the money. Well worth the investment.

This is a pretty comfortable harness, great for sport climbing or a day in the gym. I wear it all day all the time and never really have a problem comfort wise. I wish I wish I would have tried it on before buying in online, but no big deal. The harness is just a bit bigger than I'd like and I think that all things I do not like about it (can pinch my legs during some belays, especally if its I'm hanging) would be solved if I had one that fit right. Otherwise I've been pleased with this harness, I bought It at a reasonable price and have beat the hell out if it over the past year and it's been holding up great. Love having the adjustable leg loops to, big help.

I love it. Very comfortable. Can climb in it for hours. I got the 06 model with the fixed web loops, which are awesome. My only complaint is that its really hard to double back. But other than that its an awesome comfortable harness

This was the first harness I bought when I got back into climbing. I bought it without trying it on and have used it for two years for both gym and multi-pitch trad at the Gunks. It think this is a well designed and thought out product. I like the red belay loop and the upturned gear loops sheathed in plastic tubing. There was a Velcro closure that made it easier to put on the harness when it was laden with pro. But I cut it off as a safety precaution. The problem I have with the harness is the fit. I have a short waist and thick legs. Yet I can’t seem to get the adjustable legs tight enough for the leg loops to take my weight. Or maybe it’s just the rise of the harness is longer than my short waist. The upshot is that it’s uncomfortable for me to fall in and for hanging belays. So I now use it just for the gym - use a Yates Shield on the rock. If you can get a good fit in this harness, it would be a good product.
