Description Developed in collaboration with our friend Albert Muzquiz, this thermal is based on one of his favorite vintage pieces. We worked to match the original rib jacquard as closely as possible, knitting it on a flatbed machine from ring-spun, combed cotton yarn. The 310gsm fabric is then cut and sewn in Portugal. With a longer body and closer fit, it tucks in comfortably as a base layer and is the kind of everyday basic that feels just right when the temperature drops. Details 100% cotton, 310gsm rib jacquard knit Flatlock seams Mounted rib collar with triple-needle coverstitch Pre-shrunk Made in Portugal Care Wash on cold and tumble dry on low.
