One of our very favorite things (besides burritos) is discovering fantastic new fabrics — and using them in innovative ways.Like when we got our hands on exquisite Japanese flannel and transformed it into the Jaflannel Shirt-Jacket, a garment inspired by the famous hipster lumberjacks of Tokyo. Or when we took the wool of Montana’s most notorious ovine outcasts and created hoodies for the black sheep of the family.And here’s our latest curious combination of designs and materials: Dress Pant Sweatpants. More than a pair of pants, this is an experiment in sartorial subterfuge.At first glance, Dress Pant Sweatpants look like fine charcoal wool trousers. Which they are, except for the wool part.Now look closer; better yet, put on a pair.We made ‘em from high-end French terry fabric, which has a subtle heather texture that’s similar to fine suit cloth.More than a pair of pants, they're an experiment in sartorial subterfuge.They look sophisticated, but they feel as slumped-on-the-couch comfy as your favorite pair of old sweats. Whether you're in the office or on the road, rest assured that these trousers will make any day feel like Casual Friday. But no one will be the wiser.Dress Pant Sweatpants: great for dressing up or dressing down. Or just lazing around.
