A shock absorbing device to protect cryogenically frozen biological material includes an outer sleeve and a foam sleeve. The outer sleeve defines an interior volume and has an opening configured to pass a biological material container into the interior volume. The foam sleeve is in the interior volume and has an opening and an interior cavity. The opening of the foam sleeve is aligned with the opening of the outer sleeve to pass the biological material container into the interior cavity. In another embodiment, the shock absorbing device includes a first layer, a foam layer, and a liner layer to retain the foam layer. A first side of the foam layer is adjacent and facing a second side of the first layer. A first side of the liner layer is adjacent and facing a second side of the foam layer.
