This Amumu Guitar strap has a classic grid woven pattern. To give you the best comfort, we use a 2" wide black cotton webbing base for comfort and durability. To let you focus more on your play, we provide two rubber strap blocks that can be put on the outside of the leather ends to prevent the strap from accidentally falling off. To get suit most players, we use a plastic buckle, providing a 31.5" to 55" adjustable range. So it's fit you perfectly. Don’t worry if you only have one bottom strap button on your guitar, the included headstock tie can help you get you to need!
