The BAM Hightech Slim 2.9 is an ultra-light, sleek and slender case for full size cello. Great BAM look, but also very protective. Shell is made from BAM's exclusive, three-ply structure of Airex foam sandwiched between two thin ABS layers, ensuring strength and ultra-light weight. "Slim" design assures the closest possible fit, for a sleek look, easy to carry. Shell seals hermetically. Anti-slip and anti-wear patches on the outside, adjustable suspension feature inside. 9.2 lbs. Fit standard patterns, such as Stradivari, but will not hold large patterns, such as Montagana. White or blue exterior shell, black interior.
