I purchased this about 5 years ago, but I never had a chance to use it. Although it's unused, it has been stored at home for a long time, so I'll classify it as "like new." How about it for dealing with the cold in the gym during the coming season? It will be shipped via Mercari delivery. If it doesn't fit within the 3cm thickness limit, I will remove the packaging materials before shipping. Thank you for your understanding. Color: Gray
