Description

composite material with membrane

Some items, such as ski pants, footwear, tents, etc., are suitable for keeping the user comfortable. Keeping the user comfortable may include preventing the user from getting wet by rain, hail, snow, and the like. Items made from materials that are sufficiently water-resistant can keep the user dry. Keeping the user comfortable can include allowing hot air to escape so that the user can stay cool. Items made of materials that are sufficiently breathable allow hot air to escape. Improvements are needed.
