Often, I am asked about the thickness of our denim, and when I answer in ounces, no one really know what I am talking about. Since I know denim quite well, let me pass down some basic knowledge on the weight, or heaviness of denim, in general.
Raw denim, or dry denim, is measured in ounces by square yardage. For example, 1 square yard of raw denim usually weighs between 11-16oz, and can go as high as 32oz. Anything under 12 ounces is considered lightweight, between 12-16 ounces is considered medium-weight, 16 ounces and up is considered heavyweight, and 32 ounce is considered ludicrous.
The lighter the fabric, the lighter the jean, and it shouldn't take rocket appliances to figure that one out. A few things to consider when you're on the market for new jeans: lighter weight denim will break in easily, but won't produce the same fade results as a heavier denim. Lighter weight denim is much more comfortable straight off the hanger, but is less durable. Medium to heavy weight denim needs more effort to break in, but the finished product is far superior. They might be stiff and rigid at first, but wearing them in, and wearing them out, you will immediately start to feel the difference. The places that might seem a little tight at first, will start to relax, and the more you wear your denim, the more they will to form to your body.... And it's awesome.
At John Addison Jeans Co. we exclusively use medium weight denim for all of our organic raw Japanese selvedge. This guarantees amazing fades, comfort, and durability.
