What does windproof mean?
Windproof is an adjective describing clothing, shelters, structures, or materials designed to resist the passage or force of wind. It is especially common in discussions of outdoor gear and construction, where products such as jackets, tents, membranes, and façades may be advertised as windproof. In writing, the word commonly appears as a hyphenated modifier before a noun, although it can also follow a noun when the quality is being asserted: “the coat is windproof.” The term is practical rather than literary and focuses specifically on wind resistance. It is narrower than weatherproof, which can suggest protection against rain, snow, or sunlight as well. Windproof does not necessarily mean that a product is completely impermeable to air, since wind-resistant garments and buildings vary greatly in how tightly they prevent airflow. Even with that qualification, the word clearly signals an intentional barrier against disruptive wind. Its straightforward English construction also makes it immediately understandable and memorable.
adjectiveDesigned, constructed, or treated to resist the passage or force of wind.
- Resistant to the passage or force of wind.
"The hikers chose windproof jackets for the exposed ridge."
"The shelter was built with windproof fabric to protect the equipment."
"Her windproof coat kept the cold gusts from cutting through."
Windproof is a wonderfully transparent compound: wind is what it withstands, and proof is an older word for protection.

Etymology of windproof
Windproof is an English compound formed from wind and proof. Wind is an inherited Germanic word attested in Old English, while proof came into Middle English from Old French and ultimately derives from Latin probare, “to test.” In the compound, proof carries its older sense of protection or guarantee, making the word literally mean “proof against wind.” The same proof element appears in compounds such as waterproof and weatherproof, while windy preserves the wind element.
How windproof is actually used
Usually used attributively and hyphenated before a noun, as in “windproof jacket.” It can also function predicatively, as in “the jacket is windproof.” The term is common in outdoor equipment, clothing, construction, and engineering.
Easily confused with windproof
Windproof specifically resists wind, whereas weatherproof more broadly suggests resistance to adverse weather such as rain, snow, or sunlight.
