There are a lot of ads of pants manufacturers going through social media, but 1620 caught my interest. I was familiar with the special fabric blends they use, and their product is made in the USA. So I purchased the Foundation pants to see how they fit, and to see if their build is as durable as they claim. Well, I just purchased a second pair of their Double Knee Utility pants a week later. Yes, it cost more.. but the quality and type of material used makes up for the price. Plus, it's made in the USA.
