As I've come to expect from First Lite, the foundry pants are as awesome as advertised. I'm a huge merino wool fan and these pants are perfect. Love the new design of suspenders that come with them as well. To all you other First Lite fans who like their Marino line, be aware these pants don't have the stretch waist that the obsidian Merino have. These pants are built tough for any test. Highly recommend.
