what is the noun meaning of wrap?
I browse the amazon, and find a product but confused by the meaning of the word "wrap".
http://www.amazon.com/gp/product/B014IUI234, I think the products consist of two parts, a ice pack and a fabric wrap, but in the reviews, some one said "nice wrap",at this condition the wrap may mean the whole product, I want to ask the "wrap " means cloth cover or the whole product on earth.
The dictionary explains as "Wrap is the material that something is wrapped in" and "A wrap is a piece of clothing which women wear round their shoulders, either to keep them warm when wearing an evening dress, or for decoration over a coat." I am still confused.
Thank you for your help.
