Whether they are just playing in the snow or still need to figure out what snow is, the Columbia Ice Slope III Pant is one of our go-to's to outfit our kids for their snow day. Featuring a waterproof nylon fabric, the Ice Slope III Pant has our kids covered from moisture all day long. The MicroTempXF II synthetic insulation provides lightweight warmth to keep us comfortable in cool-to-cold temperatures. At the same time, the elastic cuffs and ankle gaiters help to lock in our heat and keep out the snow. The adjustable waist tabs ensure we have the perfect fit, and in combination with Columbia's OUTGROWN system, these snow pants can be lengthened to grow with our kid for years of use.
