The Craft Active Base Layer Set is a soft, comfortable performance base layer sized for kids, but packed with grown-up performance. The channel stitched fabric is soft and comfortable yet provides great warmth for cold days and good moisture management for when the little Rippers start to sweat. Stiched with a contrast thread color for a playful design, this base layer is sure to please. The Raglan sleeve design of the Top offers comfort under outer layers. The pant has an elastic waist. 2" fabric cuffs will not be too tight on the wrists nor ankles.
