“Really, really nice vest, classier than my usual fleece vest and just as warm. I’m 6’2” and weigh 185 lbs — size L fits me perfectly.”
Alex S., verified review“Bought it with a bit of skepticism because it seemed expensive. I am very happy I made the purchase. The quality is outstanding, and many compliments later.”
M. Y., verified review“The Ritter vest is a definite style upgrade to my otherwise beloved collection of lightweight down and fleece vests.”
Dan S., verified reviewThe Alpaca Rittervest™ is an alpaca-and-merino wool vest for men, made in small batches in Peru. Wear it instead of a sport coat: over a dress shirt for the office, over a t-shirt on the weekend. Warmer than wool at half the weight, wrinkle resistant, naturally odor resistant, and it doesn't itch. Hidden zip pockets, a clean full-zip front, and a felted knit that holds its shape for years. 34% alpaca, 33% merino, 33% nylon. Free US shipping, free 30-day U.S. returns and 30-day size exchanges.
