But, like another reviewer stated...the holes that hold the bottom of the mandolin are not big enough for my Loar LM-310

My son likes it second hole in leaving an extra 4 inches for those taller than us.

This strap is perfect for my needs, it has enough holes to adjust it to almost any length and it's comfortable to wear for long periods with no problem.

Well, there's a hole on the end of this that is still unused but

The bottom hole of the strap is in the exact location I need and everything just works
