E-Posto: Crafted for Comfort Created by Randall May and Yamaha, E-Posto Carriers are centered on one key element: comfort for all students. To start with, the skeletal system of the carrier is constructed of tubular aluminum — two major traits that Sweetwater percussion aces require to ensure a lightweight and fleet-of-foot playing experience. Next, E-Posto Carriers boast comfortably padded shoulder harnesses and backrests, with a handful of adjustment options such for height, shoulder width, and ab plate inversion. These features not only provide maximum comfort for percussionists of all sizes and genders, but they also actively help to combat uneven weight distribution, making for a flawless feel out on the field. As their name suggests, E Series Posto Marching Drum Carriers are designed for single-position operation with your instrument, and they are available for marching bass drums, multi-toms, and snare drums.Yamaha Randall May E Series Posto Marching Carrier Features: Lightweight
