A fine-gauge V-neck knit vest in 100% royal alpaca - the finest grade of the fibre, sorted for the softest micron. Ribbed at the neck, armholes and hem. This is not the Rittervest; it is the thing you wear under a jacket when the Rittervest would be one layer too many.
The Rittervest, 20 seconds. Warmer than wool at half the weight.
Complete the layer: Alpaca Calf Socks 3-pack
Alpaca-blend, no itch. $87 · ships free with the vest.
See the socksYes — order your usual shirt size. The fit is tailored, not boxy: sized to layer over a dress shirt or a tee, under a jacket if you need one. Between sizes? Size up if you'll wear it over sweaters, down if mostly over shirts. Free 30-day returns and exchanges either way.
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.
Ships from the US within 1–2 business days; free domestic shipping on the vest. 30-day returns and free US size exchanges. Made in Peru from upcycled alpaca and merino.
