Bam straps (set of 2) are padded, non-slip, comfortable, adjustable, and safe with high-quality carabiners. Straps are included with every new Bam case but can be purchased and used on any case with D-rings. *Note if your height is 5’5″ or under, you may want to order the SHORT set which will allow the case to rest a bit higher on your back. The straps are the same length, but the shoulder cushion is 3″ shorter. Straps should be attached at the upper D ring with the flat sides touching (see diagram).
