These straps feature a unique built in strap lock. These strap locks are much less obtrusive than other built in strap lock systems and work on virtually any guitar. Because they are part of the trap, you don't have to modify your guitar! Cotton straps are for musicians wanting a softer feel, more comfort and less shoulder slip than a poly strap. These elegant straps are made from 100% high quality, pure spun cotton fiber. The strap is 2" wide and adjustable from 36" (91cm) to 60" (152cm).
