The Raindek Leg Covering is designed to keep one's legs warm, dry, and protected regardless of the weather conditions. The product's outer shell is reportedly waterproof, windproof, and breathable. Underneath is a combination of materials that provide warmth, insulation, and a soft feel. The reinforced fabric in the feet area of the EXT models resists abrasion and tears and is water repellent. Other features include extra-large zipper and pull, welded waterproof pockets, and taped seams. The "Original" model covers the upper legs and knees while the EXT (Extreme Temperature eXperience) and the EXT Junior cover the entire leg and feet.
