The unique features of NEOTECHs Pad-It Strap make playing your instrument more enjoyable. The generous width of the neck pad [2.5 inches (6.4 cm)] helps to relieve pressure from a heavy instrument. The padded non-stretch neck pad uses high-tech memory foam to cushion your neck and shoulders. The memory foam conforms to your neck and shoulders eliminating uncomfortable pressure points. There is nothing worse than an unforgiving strap pushing a shirt button or necklace clasp into your neck. The memory foam envelops the button or clasp preventing them from being pressed into your neck. Also by conforming to the curve of your neck and shoulders the memory foam distributes the instrument's weight over a larger surface area. This avoids uncomfortable pressure points. The memory foam is antimicrobial and wicks away moisture to help keep you cooler. Enjoy playing in long gigs with this comfortable and secure strap.
