Infant outerwear is downright adorable, and when it has technical chops to boot, well that’s just our favorite! As cozy as it gets, the namuk Zack Winter Overalls are well insulated with PrimaLoft Eco insulation and well protected thanks to fully taped seams, a PFC-free DWR treatment, and 15K waterproof face fabric. Extremely attentive down to the smallest details, the Zack Winter Overalls from namuk are just as appreciated by the parents as they are by our little ones.
