Style 472041, currently on the Athleta website, the Pinnacle trouser is a wide leg hybrid trouser with a regular trouser front fly and waistband and an elasticized back waistband. The fabric is what Athleta calls Italian Eurolux, 68% nylon and 32% spandex, which the website indicates is breathable and that airflow moves easily through the garment . I wore these one time before I concluded they were too big and repurchased a size smaller (yay, weightloss is working). These are freshly laundered and they are a travel dream, easy wash, quick dry, no wrinkles. Size 10 petite; 28 inch inseam. This pair is navy. I also have a black pair listed.
