Our warmest Regulator'\\" insulation allows you to embrace the midwinter wildness of swirling snow and sparkling ice. Made from improved high-pile R2 (double the fiber loft), the Body Rug fabric is now lighter, more com- pressible, breathable and stretchy. For reduced bulk and increased mobility, we use Rico stretch panels in the armpits, cuffs and hem. With a deep, ventilating front zip. The trim cut accommodates a shell while allowing for a light base layer. Made in USA.
