Unveiling Raincoat Structures: Which One is Right for You—2-Layer, 2.5-Layer, or 3-Layer?

The "layer count" of a raincoat directly affects its waterproofing, weight, and price. This article will delve into the differences between 2-layer, 2.5-layer, and 3-layer raincoat structures to help you find the perfect style for your needs.

1. 2-Layer Raincoat: Quiet and Durable, Ideal for Urban Use

Structure: A membrane or coating is applied to the inner side of the outer fabric, forming a single-layer fabric. The inner layer is equipped with a loose lining to protect the membrane or coating.

Pros:

✓ Affordable
✓ No noise when walking

Cons:

✗ Slightly heavier
✗ Average breathability

2. 2.5-Layer Raincoat: Ultra-Light and Packable, Best Value Choice

Structure: Similar to the 2-layer and 3-layer structures, this design uses a lightweight, durable outer fabric as the first layer. The second layer is actually a polyurethane laminate or coating applied to the inside of the first layer. Finally, a protective gloss or print layer is added to the second layer (the "half layer").

Pros:

✓ Extremely lightweight
✓ Ideal for backpackers

Cons:

✗ Lower durability
✗ May feel damp to the touch

3. 3-Layer Raincoat: Top-Level Protection, The Professional's Choice for Outdoor Use

Structure: This product does not use any coatings; instead, a thin membrane is tightly sandwiched between a durable outer fabric and an inner lining.

Pros:

✓ Most waterproof
✓ Most durable

Cons:

✗ Expensive
