The invention relates to a portable personal cryogenic container for carrying materials at low temperatures, and more particularly for carrying cryogenically preserved materials. The cryogenic container can be formed from an external shell assembly having multiple parts, where the parts are interlocked to support an inner container. An elongate receptacle holding preserved materials may be supported in the inner container alongside cryogenic fluids for maintaining cryopreserved materials.
