The Speed Convertible series are hybrid shoulder bags/belt packs designed for photographers who value versatile and ergonomic camera bags. First and foremost a contoured shoulder bag, the Speed Convertibles keep photo gear readily accessible. The wide opening flip-top design hinges away from the body to rapidly work in and out of the bag. As a shoulder bag, the Speed Convertibles offer durable zippers, a secondary main compartment entry, and multiple pockets for small accessories. A cushioned shoulder strap with a long section of padding maximizes comfort while carrying the bag in different positions.To adapt a Speed Convertible bag as a belt pack, deploy the integrated waist belt which is conveniently concealed in two zippered pockets on either side of each Speed Convertible bag. Fastening the flexible belt around the waist provides better stability while walking, especially when used in tandem with the included shoulder strap. The waist belt also features Modular rail sections for attaching Modular, Skin or Multimedia components to increase gear carrying capacity as needed. The three bags in the Speed Convertible series, Speed Demon V2.0, Speed Freak V2.0 and Speed Racer V2.0 offer photographers choice of the right bag size to suit their equipment and the adaptability for a variety of different assignments.Top Features: Easily converts from streamlined shoulder bag to functional belt pack Integrated waist belt "disappears" by tucking into zippered size pockets Modular rails built into waist belt for adding Modular Rotation System components to increase gear capacityGear Profile: One standard size DSLR plus 2-3 small zoom or prime lenses Smallest size bag in Speed Convertible series Technical Specifications: ID: 9.3" x 6.8" x 5" (23.5 x 17.15 x 12.7 cm) ED: 12" x 8.5" x 8" (30.5 x 21.6 x 20.3 cm) Weight: 1.6-2.1 lbs (0.7-1.0 kg) Lifetime Warranty
