Did you know great brands now make ultra-compact jackets with unparalleled waterproofing from 2.5 layer fabric? New to the outerwear market in the past few years, 2.5 layer fabric has made staying dry easier outdoors, without adding bulk and weight.  So if you’re after a high performance waterproof, lightweight jacket, here’s everything you need to know about 2.5 layer fabric and why it’s a must-have for your next outerwear purchase.

What is the best lightweight raincoat fabric? 

2.5 layer fabric is the gold standard in modern outerwear technology. If you’re wondering how a fabric can have half layers, it’s a fair question; 2.5 layers refers to the clever construction techniques used for high performance jackets. This new construction style promises better waterproofing, breathability and packability than the old-style 2 layer fabrics that used to dominate the outerwear market. 

At Rainbird, we design 2.5-layer fabric to be ultra-lightweight, making it very compact to store without compromising functionality in the weather. Here’s how it works:

• First layer: Low-weight face fabric.
• Second layer: Polyurethane-based waterproof and breathable (WP/BR) laminate or coating.
• Half-layer:
• Bare-minimum protective inner layer, more like a sheen than a full layer.
• Typically consists of dots, a grid pattern, or a scattering of resins.
• Provides a touch of slickness and abrasion resistance.

• Key characteristics of 2.5 layer raincoat fabric
• Ultralight, typically 16 ounces or less.
• Ideal for ultralight wilderness travel.
• Suitable for weight- and space-restricted travelers.

• Performance of Rainbird fabric with 2.5 layers

• 8,000mm waterproof rating.
• 5,000mvp breathability.
• Fully seam-sealed inner construction.

Why are 2.5 layer raincoats different from classic raincoat fabric jackets?

It's all about the extra "half layer." The fabric’s actual construction fairly closely resembles traditional 2-layer jackets and raincoats: Featuring an outer face fabric and a waterproof/breathable membrane. However, instead of the traditional hanging mesh liner found in 2-layer designs, it uses a printed or sprayed-on "liner" to protect the membrane.

One of the most popular waterproof jackets for women is Rainbird’s Agena jacket. We make it from ultra-lightweight 2.5-layer fabric, and the outer face fabric features a ‘quiet material.’ This means no annoying ‘swish swish’ as your arms rub on your torso with each step. As promised by 2.5 layer fabric, the Agena is ultra compact for easy transportation. And thanks to its streamlined silhouette, it has a flattering cut and feminine silhouette.

Easily packable into a day pack or the seat pocket of your car, the Hadar is a flawless raincoat without looking like an old-school waterproof jacket. This is thanks to lower body pockets and a low drop hem.
