The 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.

No. The fabric is a superfine alpaca-and-merino blend (34% alpaca, 33% merino, 33% nylon for durability) with a hand-feel close to cashmere — soft against skin, and naturally thermoregulating: warm on the platform, not sweaty in the office.
It's the piece Forbes called "a wardrobe staple for the modern working man." Clean lines, no logos, hidden zip pockets — it sits over an oxford or under a blazer as easily as over a tee at the weekend.
Two hidden zippered hip pockets, open hand pockets, and an interior pocket for phone, keys or cards. The front zip is a two-way (double-pull) zip so you can vent from the bottom when seated.
Rarely — the fabric is stain, water and wrinkle resistant and naturally antimicrobial. When you do: cold hand wash or wool cycle, lay flat to dry, no tumble.
