Built with Comfort-First technology We had a simple goal when we designed our Comfort-First™ Knockabout™ Chinos: to make wearing them – and consequently everything you do WHILE wearing them – more comfortable. We’re expanding that even further this go-round with a small change that makes a big difference: an extra bit of spandex bringing the total up to 3%. If you thought they were comfortable last gen or if you’ve yet to give them a try you’re in for a treat. These are more comfortable than any pair of pants has a right to be. And with our classic tailoring they look every bit as good as they feel. .
