To wear the Axel sweater, simply pull it over your head. You can fasten the bamboo buttons at the neckline to your preference. It's great on its own in milder weather or layered over a long - sleeved top when it's colder. As for care, it's best to machine wash it on a gentle cycle with cold water. Avoid using bleach as it may damage the fabric. After washing, reshape the sweater while it's damp and lay it flat to dry. This will help keep its shape and the cable knit pattern looking sharp. Also, don't iron it directly on the bamboo buttons; if you need to iron, turn the sweater inside out and use a low - heat setting.
