Very comfortable. I ordered a large even though I am usually a medium so I could wear a shirt underneath and it's perfect.

Like the title says I cannot complain about the Hardware it works great no issues. But the software something called 'smi superviewer/multiviewer' starts loads my camera views but if i try to do anything it wants a username and password which I've tried every possible combo i can think of to no result. I believe i will be returning it.
