The Pedi Viola Elegante shoulder rest has a titanium alloy carbon fiber body. Very comfortable and lightweight at only 2.5 ounces; replacement sponge layer included.
Violin model pictured; viola model varies slightly-brackets have 5 screw positions
Love this shoulder rest - nice and light, very grippy feet. Seems to impede my viola's sound less than any other shoulder rest I've used. I feel that the instrument is a bit more responsive than with other ones.
