The Capilene Midweight got a minor update, pictured above. It's essentially the same top, with a minor adjustment to seam placement and some new colors. Because this new model and its predecessor offer extremely similar performance, we recommend snagging the older version at massive discounts while it still lasts. Our purchase links lead you to both versions.
Our favorite product for combining performance with a low price is The North Face Warm, our Best Buy award winner. If you want to stick with fast-drying, thin base layers, the Rab Merino+ 160 is an excellent top that performed better than the Capilene Midweight.
