Everbreath Photon Pants - Long
This long-selling stretch rainwear has been redesigned to introduce new advancements. The latest update enhances waterproofing, durability, and breathability, setting a new standard for stretch rainwear.
Next-Generation High Water-Resistant Zipper – AquaGuard® Tightened
Developed in collaboration with YKK, this newly upgraded water-resistant zipper provides exceptional rain protection without requiring an inner flap. Even under strong wind pressure along ridgelines, it effectively prevents water from seeping in.
The Inner flap-free design also eliminates fabric snagging, ensuring smooth, hassle-free operation when opening and closing. By reducing excess material around the zipper, this design creates a sleek, minimalistic silhouette with reduced bulk.
Improved Core Performance for Extended Rain Protection
This update enhances waterproofing, breathability, and stretchability, working together to provide greater confidence and comfort on long hikes in continuous rain.
The Everbreath® membrane, made from a polycarbonate-based polyurethane microporous film, delivers top-tier waterproof breathability while maintaining exceptional durability against hydrolysis, ensuring long-lasting performance. The fabric structure has been reengineered with optimized yarn selection and weaving, improving resistance to repeated stretching, abrasion, sweat, and body oils.
As its name suggests, Everbreath® technology provides continuous breathability, preventing stuffiness during activity. Both the outer and inner layers feature a durable water-repellent (DWR) treatment, reducing water film formation to maintain long-lasting breathability.
With 107% vertical stretch and 117% horizontal stretch (JIS L 1096 standard), this rainwear moves effortlessly with your body, ensuring unrestricted mobility in any direction. Whether navigating technical terrain or enduring harsh weather, it allows smooth, natural movement without restriction.
The soft knit lining further enhances comfort by reducing stiffness, delivering a gentle, non-restrictive feel that moves seamlessly with every step.
Additionally, precision-engineered seams, optimized patterning, and streamlined fabric construction contribute to an ergonomic fit, minimizing bulk while allowing free, unhindered movement, even in strong winds and heavy rain.

**Special Zipper Structure & Handling
AquaGuard® features a unique interlocking structure at the center of the zipper tape, enhancing water resistance. Due to this advanced design, its handling and storage differ from conventional waterproof zippers. To maintain long-term performance, please follow these care guidelines:
[Keep the Proper Zipper Alignment]
If the water-resistant tape misaligns or loses its shape when closed, slide the zipper again to restore proper alignment and maintain its intended function.
[Avoid Heat Exposure]
Do not iron or tumble dry, as heat may deform the zipper structure.
[Check Before Use]
Before using the product, please review the care, usage, and storage instructions provided.
Features of EVERBREATH® Outer Shell
No more bulky, constricting outer shells
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.
