Our team at work used this harness for confined space and container works. It is comfortable for hours at a time. It is easily adjustable for various waist and leg sizes. The sizing is easy. For most average guys, size 2 will adjust and fit well. For most average gals, size 1 will fit just fine. Most of the guys on the team has waist between 34 to 38, and size 2 have plenty room on both end of adjustment. I borrowed a size 1 for my teenage daughter to climb wall in gym, and it fitted perfectly for her.
Well constructed with comfortable design. You cannot go wrong with this harness.
