With the Namuk Mack zip-off pants, your little one can start a cool morning and simply zip off their trouser legs in the hot afternoon. The Mack is made from a durable cotton blend fabric with Cordura content, which makes them particularly hard-wearing. The trousers have an elasticated and adjustable waistband and elasticated leg cuffs - as long as the trouser legs are zipped up. They also have two bags at the front and two at the back.
