Warm covering (6)

Ross

I believe the answer is:

cocoon

(Other definitions for cocoon that I've seen before include "Protect" , "Pupa's protective case" , "Protective cover of silkworms, etc" , "Envelop for protection" , "Protective case for insect" .)

I've seen this clue in the Evening Standard.
