Clean lines, stretchy, breathable, the Craft Adv Tech Fleece Thermal Women's Midlayer is the essential lightweight sweater for athletes looking for a layering piece that performs under another layer as a midlayer, over a baselayer on its own0 from the first chill days of autumn through your cross-country ski adventures, and off into summer summits, this is a perfect year around piece. Our favorite detail? Thumbholes, which means when you slide this layer under another it fits smoothly. No bulking up around the shoulders or arms, so no chaffing, even under pack straps. A level up layer with wicking, fast drying, and breathable side and underarm panels for optimal temperature regulation, this is an essential gear bag sweater that unfurls to reveal a classy looking layer that’s ready for a workout, or to be your post-workout warmer. Craft is a European company, so this is cut with a semi-relaxed fit, but tends to run smaller than conventional US sizing, so if you’re between sizes, or like a looser fit, size up. A favorite piece for its cozy wearability that is ready to take on fast tracks in winter cold and add a layer of cozy when you’re out in an autumn chill.
