Able to fit one alto saxophone, the Gard 104-MCSK compact alto saxophone case uses a patented mid-bag suspension system, foam belts and pads and cone inserts to protect your instruments. The exterior is made of 1680 denier ballistic synthetic fabric, standard in all Gard Synthetic bags, including on the 104-MCSK. This fabric is abrasion- and tear-resistant. The 20 mm padding is made up of dense, thick and impact resistant High-Density foam setup on all sides of the instrument. A 1” zipper guard protects the instrument from accidental scratching from its metal zippers.
