Bought this vest in black to replace my 10-year-old vest that has lost too much down. Love the thermoball concept, but the fit was unacceptable. The trim at the waistline seemed disproportionately small compared to the rest of the vest. The waist was snug, but the shoulder area was bulky. I tried going down in size to see if that would resolve the issue, but instead found the waist line to be almost too tight to zip. I returned it as I didn't like the fit.
