AMAZON BRAND IS FANTASTIC. I bought one of these sweaters for my husband.Warmth: It's a year round weight in the South and Spring/Summer weight for the North, and not designed for cold weather (buy wool for that).Fit: It fits so well and felt so soft, and the color was so good that I bought him three or four more. I had bought him a similar sweater in a different color (same fabric, same style) from Ralph Lauren Polo. The only way I can tell which is the Amazon brand and which is the Ralph Lauren brand is by the color.Value: All the Amazon brand sweaters I bought, added together, cost less than the single Ralph Lauren brand.As far as durability goes, time will tell. I ruin every sweater I wash so we send all our sweaters to the cleaners. I don't know what would happen if they (either brand) were washed. Shrink? Lose color? Fall apart? Look for these considerations in another review.Bottom line, this Amazon brand is amazing. I highly recommend buying the sweater and hope Amazon will offer it in more colors.
