SKB Soft Cases feature a rugged, weather resistant 600 Denier ballistic nylon exterior with a hard-core EPS foam interior to provide more substantial protection than a conventional gig bag. The exteriors feature two zippered pouches, one with numerous internal compartments for organized accessory storage, and an adjustable padded backpack strap for easy transport. The plush lined hard foam interiors are the same as those found in SKB hardshell cases and offer full neck support to cradle the guitar neck more securely than a conventional bag. 1SKB-SC30 fits most thin-line classical acoustic/electric style guitars
