Apparel is the term used to describe pieces of material that are crafted to be worn on the body. Apparel items include (but are not limited to): tops, bottoms, skirts, shorts, sweaters, and swimwear.
Outdoor refers to apparel, accessories, or footwear suitable for use in recreational or athletic activities in open air, outdoor environments. Since outdoor activities such as trail running, climbing, or hiking are often performed on uneven, rough terrain or slippery surfaces, outdoor shoes tend to offer better performance through an array of specific features designed to provide extra support, stability, and traction. Other types of outdoor activities such as camping, fishing, canoeing, backpacking, or kayaking may also require specific types of apparel and accessories.
