To keep Oakis clean and in good working order, it’s recommended to hand-wash them with a mild detergent and then let them air dry. A rinse-off outside or in a sink would be a good first step if they’re super muddy! If you do need to pop them in the washing machine, first zip them up and turn them inside out, then wash on a gentle cycle. The less they’re washed and the gentler they’re dried, the better they’ll keep everyone dry and happy!
