The Brooklyn-based Outlier, purveyors of super clean and functional cycling apparel, has you covered when it comes to layering just right for your morning ride to work, for coffee, around town or wherever you might be headed on two wheels.
The Soft Core Wool Vest, an experimental run of a dozen made in California, is a soft core of knit superfine New Zealand merino on the inside, an outer face of virgin wool flannel and a 120 gram, military-grade Primaloft Infinity insulation sandwiched between. Nice and warm, but designed to avoid overheating.
Pull that on over the Long Action Merino Tee, ultrafine 17.5 micron New Zealand merino base layer with a gusseted sleeve and dart contoured shoulder, and you're on your way.
Both available via Outlier's web shop.
