Heads-up: our favorite midwestern purveyors of next-level basics, NWKC, just dropped a new collection of heavyweight – and very winter-ready – Wool / Nylon blend Sweats. Made in the USA, of course, the full-zip tops and slim-fit trou are made from a proprietary fabric that has nylon-wrapped merino on the exterior, poly on the interior, and stretch nylon connecting the two, making these warm, weather-resistant, and tough as hell. Three styles in four colors are available. Hop to it.
