Most arm warmers are simple fleece-backed stretchy fabric or plain-knit tubes, which makes these high-tech knitted sleeves from Craft an immediate hit.
Multi-weave and density body mapping design has been used in socks for a while, but this is the first time we’ve seen arms benefit. Thicker knit on the back and bands on the inside of your elbows keep them close-fitting and wrinkle-free. The fit is excellent, and silicon grippers stop them sliding down, too.
They stay cosy when wet and dry really fast, making them great three-season shirt extenders, even under a jacket. When compared to basic alternatives they offer great value as well.
