Maggie's Organics mid-calf crew socks contain 99.8% Organic Cotton and only 0.2% Spandex (at the top of the sock). We've been Maggie's fans for years and decided we needed to share them with you all. The softest, coziest, OG organic crew socks. Did we mention they're also great for skin sensitivity?! Loose fit, rib knit. Made in the USA.
