I purchased this from the BILLABONG official website this month. I intended to use it for snorkeling during a trip, and my husband wore it there, but unfortunately, the size was too big for him, and he only used it for an hour. I have since washed and stored it. I would like to offer it to someone who plans to use it for travel during the New Year's holiday and whose size fits.
