A poncho is a simple piece of clothing made from a single large piece of fabric with a hole in the center for your head. You pull it on over your clothes, and it drapes down over your shoulders and body like a blanket you can wear. Ponchos keep you warm and dry without restricting your arms the way a jacket does.

The poncho originated in South America, where Indigenous peoples in the Andes Mountains wore them for thousands of years, often woven from llama or alpaca wool in beautiful patterns. Spanish explorers adopted the design, and it spread around the world because it's so practical: easy to make, easy to wear, and surprisingly effective.

Today you might wear a plastic rain poncho at an outdoor concert or football game, or pack a lightweight one for hiking. Some ponchos are fashionable garments made from wool or other fabrics, while others are purely functional emergency rain gear. The poncho's brilliance lies in its simplicity: one piece of waterproof or warm material can protect your entire upper body, and when you don't need it, it folds up small enough to stuff in a backpack.
