windbreakers

Windbreakers, or windbreaks, are structures or garments designed to reduce wind exposure. The term commonly refers to two distinct uses: windbreak clothing worn to resist gusts, and windbreaks used in landscapes or built environments to lessen wind speed and its effects.

As clothing, windbreakers are lightweight jackets made from synthetic fabrics such as nylon or polyester, often with a thin lining. They block wind while remaining breathable and compact, and may feature a front zipper, elastic cuffs, a stand-up collar or hood, and water-repellent finishes. They became popular in the mid-20th century with outdoor and athletic wear and are used for running, hiking, and travel. Care usually involves machine washing and avoiding high heat to preserve coatings.

In landscape and agriculture windbreaks are rows of trees, shrubs, or constructed barriers placed to reduce wind speed across an area. They protect crops and soil from erosion, reduce evaporation, improve microclimate, and shelter livestock and buildings. Design considerations include species selection, height and density, spacing, wind exposure, and local climate. Windbreaks may be natural belts or artificial structures such as walls or fences. They require maintenance to manage growth, pests, and disease.

Effectiveness depends on wind direction, speed, and the geometry of the break. Windbreaks can create turbulence at leeward edges or accumulate snow and debris. Implementation should align with environmental regulations and land-use goals.
