Abstract: A cover for placement on a compressed gas bottle is dimensioned to closely conform to the shape and size of a top section of a compressed gas bottle with a control valve assembly installed thereon. The cover preferably includes a shell having first and second shell members connected by a living hinge, a plurality of clasps for holding the first and second shell members together in a closed configuration of the shell and a handle for carrying the cover and a compressed gas bottle to which it is closed upon. The upper portion of each of the first and second shell members are preferably lined with a resiliently compressible foam for cushioning against a control valve assembly of a compressed gas bottle. In a preferred embodiment of the cover, each of the first and second shell members has at least one friction band of a rubber or elastomeric material disposed therein for compressibly contacting a compressed gas bottle and thereby resisting slippage of the cover with respect to the compressed gas bottle.
