Quince Baby Alpaca-Wool Diamond Stitch Crew Sweater Size small Color Light Gray Soft, textured, tactile. We love that our alpaca crewneck sweater has an oversized silhouette with a light feel. It has a diamond stitch pattern with an incredibly soft texture for ultimate easy styling and comfort. Alpaca wool is long lasting and resistant to pilling, and doesn't have the scratchiness of some other wools.
