Waterproof yet Breathable for Maximum Comfort & Unrestricted Movement

Typical outer shells are uncomfortable to wear due to stiff fabrics that lack stretch and restrict movement. To address this issue, Finetrack® developed EVERBREATH®, a waterproof and breathable fabric that offers excellent stretchability. This innovative material allows for unrestricted movement, ensuring ease and comfort during outdoor activities. With Finetrack® Outer Shell incorporating EVERBREATH®, you can enjoy your outdoor pursuits without the discomfort of constricting fabric, allowing you to fully focus on your outdoor experience.

Features of EVERBREATH® Outer Shell

No more bulky, constricting outer shells 


(Background of L5 Development)

When faced with a long, steep trail in the harsh rain and wind, and you put on your outer shell, what do you look for in that garment? In what other way can an outer shell make a difference on your trek, other than via top-quality waterproofness and breathability?Waterproofness and breathablility are both must-have qualities of standard outer shells, but to enhance protection and comfort, EVERBREATH® aims to break away from bulky, constricting shells to achieve ease of movement.

It has a different dimension of stretchability that follows large movements on rocks and chains without straining when raising the thighs or swinging the arms, so the stress on the body is reduced and the performance can be maximized. increase. In addition, the silhouette that follows the body line prevents the hem from becoming loose and flapping in the wind, so it can be used not only as rainwear but also as a wind shell.

Abundant flex and stretchability

The waterproof breathable membrane of EVERBREATH® itself offers uncanny stretchability, providing a supple texture and feel without compromising the stretch and flexibility of the other fabrics in your layering system.

The Finetrack® OUTER SHELL's next-generation waterproof yet breathable membrane for superior performance and durable longevity

In the outdoor community, it's generally accepted that the waterproof pressure required for climbing in the rain is 10,000 mm or more in situations where extra pressure may be simultaneously applied from movement. With a rating of 20,000mm, EVERBREATH® is not only designed to withstand twice the required amount of pressure, but also to maintain its functionality for a long time.

Continuous Breathability

Our Finetrack® Outer shell prioritizes the user experience by ensuring exceptional moisture permeability in various weather conditions, including rain and snow. We assess moisture permeability using the JIS L 1099 A-1 method, which closely simulates real-world wear. Achieving a moisture permeability value of 10,000g/m2/24hr through the A-1 method represents top performance. Unlike the commonly used JIS L1099 B-1 method, which can yield higher values but may result in stuffy fabrics during actual use, we employ the A-1 method to accurately measure the moisture permeability value of EVERBREATH® in real-world conditions. EVERBREATH® demonstrates a breathability of 10,000g/m2/24hr using the A-1 method.

Powerful water repellent treatment on both sides

EVERBREATH® has a strong water repellent finish, not only on the front side of the fabric, but also on the reverse side. The water repellency on the reverse side is a specification unique to Finetrack®.Even in situations where the underside of the shell gets wet from perspiration moisture and vapor from the interior layers during exertion, from rain finding its way in from outside, or both, the water repellency of the lining allows breathability to continue while preventing the formation of a moisture film that would reduce functionality in typical fabrics.

Polycarbonate-based polyurethane that achieves high-performance flex, stretch, and durability

Finetrack® developed the innovative EVERBREATH® material, made primarily from polycarbonate-based polyurethanes, as a waterproof yet moisture permeable, porous membrane .

EVERBREATH® boasts an ideal balance of functions

The main materials commonly used for waterproof breathable membranes include polyurethane-based (PU) porous and non-porous membranes and fluoropolymer (ePTFE)-based porous membranes. Polyurethane-based membranes are stretchable and moisture permeable, but are vulnerable to degradation over time due to hydrolysis. Fluoropolymer (ePTFE)-based materials are made by laminating thin films of fluoropolymer (typified by Teflon), and have high moisture permeability but poor stretchability and a tendency to feel tight during wear. That's why Finetrack® developed its high-performance EVERBREATH® material using polycarbonate polyethylene terephthalate, to achieve that sought-after balance of water resistance, breathability, durability, and comfort, without any feeling of tightness or constriction.
