Sweatpants not very heavyweight and are very good to wear to fitness center. They fit very good and can be worn anywhere. A back pocket would be good as they only have 2 frount pockets.
Worn for nothing more than winter weekend loungewear (and only 2-3 dozen times at that) and the waistband stitching unraveled beyond wear or repair. The fabric is incredibly comfortable offers 4-way stretch, but the durability is non-existent. Honestly, the most rigorous activity they were put through was in the washing machine. Accounting for what I paid for the pants, alterations to hem the legs to a wearable length, and now replacing them when everything but the waistband is still in like-new shape, I could have easily bought a pair of high-performance pants from one of the premium brands. Very disappointing.
