Workman Merino Tech (R) Active Insulation Stand Vest, Navy, Size L. This item is rare and I purchased it on hold, but it didn't suit me, so I'm selling it. This is a limited production item, and there are almost no models in stock at the store. ● Product Features ● Combines breathability and heat retention!
