Terramar Ecolator 3.0 Pant is super cozy extra comfort for those kids who complain of the cold, or those who are outside no matter what the weather, and what the thermometer is saying. The interior of these pants feature a wide grid pattern in a soft loop designed to both trap air for extra warmth when necessary, and release heat and wick as the wearer gets hot. How can this be? Proprietary ClimaSense® Thermoregulation Technology fabric is designed with adaptable fibers, engineered to recognize the individual’s skin temperature. The fiber structure contracts to trap air and generate heat when skin is cool, expands to allow heat and moisture vapor to escape when the skin heats up. Yes, it’s as amazing as it sounds, all the tech you’ve come to expect in your own clothing, sized down to fit your child and keep them comfortable no matter what winter is throwing at them. This is the pant for the kid that is out there in all weather, the child who complains about being cold, and the child not accustomed to cold weather. A lovely warm pant that can double as leggings and lounge wear on the off days when not put to use outside.
