Insulating device

A method comprising:

• forming a body assembly by forming a lower outer shell, placing a lower insulating layer and an aerogel structure into the lower outer shell, and securing a lower inner liner portion to the lower outer shell, wherein the aerogel structure comprises skiving features that extend from a surface of the aerogel structure to a mid-point width of the aerogel structure and are configured to facilitate folding of the aerogel structure, wherein the aerogel structure is surrounded by an external shell within the lower outer shell, and wherein the aerogel structure is not attached to the external shell;
• forming a lid assembly of an upper outer shell, an upper inner liner portion and an upper insulating layer and an aerogel structure therebetween;
• and
• joining the lid assembly to the body assembly by securing a closure between the lid assembly and the body assembly and by securing a binding material to the body assembly and the lid assembly.
