Paca size medium men’s. 100% alpaca wool. This was my favorite sweater but I lost weight and now it’s too big 🙁. It’s so unbelievably soft! This was made by Peruvian women in Peru. The warmest sweater I own! Great used condition. It has a cool alpaca design going up the middle of the sweater. Measurements are pit to pit 20. Collar to bottom of sleeve 30, collar to bottom of sweater 28.
