I use one of those Realtree Hunters Safety Systems. It's a harness made into a light vest which makes getting in and out of MUCH easier than other harnesses. No tangled up straps and such. It's not cheap but it is highly functional and comfortable to wear. Whichever harness you decide to get, get a FULL body harness. And also make sure it has the shock absorbing fall system. Lot of back injuries from falls in harnesses without those.
