This is one of my most worthwhile clothing purchases! Though not heavy weight, my Carhartt is the warmest coat I own, keeping me toasty in single-digit temperatures. The outside is durable and does a fantastic job of blocking wind. I would only recommend that any pet owners not purchase black, because pet hair has a tendency to stick.

My nephew asked for this coat for Christmas. I couldn’t believe the quality when I got it in the mail. We are outdoor people, and we have many labradors. The fabric is so tough that no branch or dog jumping up can damage it. It’s got a waterproof coating so rain beads off. This coat was made to last forever, it’s very warm, and it looks good to boot. He hasn’t taken it off yet. In fact, he asked for the same fabric coveralls to wear over the jacket for brush clearing work in the extreme cold.

The duck fabric is indestructible; the “sandstone” is a softer fabric. The regular duck is still comfortable; just wanted you to know the difference. I don’t think that the microsanded one would last as long, but if you’re just wearing it for looks and not rugged work I would say it’s okay.
