Is the D-Belt comfortable?

Yes it is!  Most of us wear one daily here in the office.  The belt is extremely comfortable, and holds up to extended wear.

The poly liner is flexible with your body movements, and doesn't dig into you.  It remains rigid enough when it counts, but it's comfortable enough for all day wear.  

These belts are really great, try one out and if you don't like it immediately we'll take it back.
