Breath Straps is perforated with 265 holes and inserted a special waterproof and breathable membrane inside it, allowing the shoulder to breathe while preventing sweat from entering the Strap. The true benefit of this system is that it keeps strap and shoulder dry of course, depending on your sweat and the movement and time you keep the strap in position, but of course this will be an advantage in keeping you much more comfortable while playing.Breath Strap is a vegan strap, super lightweight and padded, it's not comparable with any other bass strap on the market. The strap is 8cm wide with adjustable range of 103 to 130cm. We made this strap thinking on bass players and the weight they normally have to support when they play, this does not mean that this strap is not suitable for guitar players, of course it is!
