All RB Continental cases feature a Ballistic Quadraweave exterior, quilted "double helix" velvet interior, high-strength corded edges and seams, and double-stitched with high tensile thread and reinforced at tested stress points. This mandolin case has a thick shock-absorbing Flexoskeleton with reinforced impact panels, a neck brace suspension system with an adjustable locking security strap, and rubberized foam headstock grip. The adjustable, padded hideaway backpack straps makes traveling with this beauty a breeze. Each case is reinforced at tested stress points and double stitched with extra-strength high tensile thread. A knurled abrasion grid on the top and bottom resists scuffing, and interior pads at the headstock and endpin provide long lasting protection. The case is finished with custom plated hardware, including industrial strength zippers and a Zero-G palm-contoured handle with weight distributing foam core for unsurpassable longevity and comfort.
