A windbreaker is a lightweight layer that reduces wind chill and adds light protection without the bulk of a waterproof shell. It is useful for running, hiking, cycling, travel and breezy everyday conditions.

Compare wind resistance, breathability, fabric weight, packability, ventilation and water repellency. Highly windproof fabrics can trap more heat, so active users should look for breathable panels or ventilation details.

Windproof, water-resistant and waterproof describe different levels of protection. A windbreaker may handle brief drizzle but usually lacks a waterproof membrane and fully sealed seams. Its main advantage is light, breathable protection that is easy to carry.
