The BG Clarinet Zen Strap will provide premium comfort while holding your instrument. A spacer rests on your chest distributing the weight of your clarinet away from your neck to prevent any strain. Inside the nylon strap is a sponge padding that will absorb any sweat and provide further comfort to your neck. The sling is non-elastic - an elastic version is also available if you prefer. Two leather connectors are included for attaching to your clarinets thumb rest.
