Fleece jackets are synthetic, polyester-based garments known for being lightweight, highly breathable, and warm, even when wet. Key features include excellent moisture-wicking, fast-drying, and versatile layering capabilities, making them ideal for outdoor activities. They are generally durable, soft, and easy to maintain.

Key Features of Fleece Jackets:

Warmth-to-Weight Ratio: Engineered to provide significant insulation without the weight or bulk of traditional wool, retaining heat even when damp.

Breathability & Moisture-Wicking: Highly breathable, allowing sweat to escape during physical activity, which keeps the wearer dry and comfortable.

Durability & Maintenance: Resistant to wear and tear, and typically machine washable. Many have anti-pill finishes to prevent bobbling.

Layering Versatility: Frequently used as a mid-layer under hardshell jackets or as an outer layer in milder, dry conditions.

Water Resistance: While not fully waterproof, the synthetic (hydrophobic) fibers repel water. Some specialized fleeces include water-resistant coatings.

Functional Design: Common features include full-zip or quarter-zip closures, high collars, zippered pockets for storage, and sometimes, windproof membranes.

Weights: Available in different weights—microfleece (lightweight/active), mid-weight, and heavy-weight for maximum insulation.
