I have been looking for a permanent, heritage-quality sweater for a while, and the Sol Alpaca Classic finally fit the bill. The difference with Baby Alpaca is immediate; it regulates heat incredibly well without the bulk of a heavy wool knit, and the texture is genuinely smooth against the skin with zero itch. I’m a standard size 36 (Small) in t-shirts and ordered the Small here, and the fit is spot-on—tailored enough to look sharp but with enough room to move. It feels like a piece built to last decades, not seasons, and has quickly become the anchor of my winter wardrobe.
