Where precision engineering meets environmental extremes. Every technology in our lab exists for one reason — to keep you performing at the edge.

Innovation Lab

Core Technologies

01

StormShield™

Advanced waterproof-breathable membrane with microporous structure that blocks water molecules while allowing vapor escape. Lab-tested beyond industry standards.

02

ThermalCore™

Heat-reflective insulation system using synthetic micro-fibers that trap body warmth while remaining compressible. Delivers maximum thermal efficiency per gram.

03

BreathFlow™

Dynamic moisture-wicking fabric architecture that accelerates sweat transport away from skin. Air-channel construction creates continuous ventilation during high-output activity.

04

LayerSystem™

Modular garment architecture where base, mid, and outer layers are engineered to function as an integrated climate-control system rather than isolated pieces.

05

RangeGuard™

Durable water repellent (DWR) finish free of PFCs. Environmentally responsible treatment that maintains beading performance through extended field use.

06

TerraDura™

Abrasion-resistant textile reinforcement at high-wear zones. Cordura-grade durability without compromising weight or flexibility. Built for rock, ice, and abrasive terrain.

Material Science

3-Layer Construction

Outer Face Fabric
High-denier nylon face with RangeGuard™ DWR treatment. First line of defense against rain, snow, and abrasion.
40D–70D Nylon
StormShield™ Membrane
Microporous waterproof-breathable barrier. Blocks liquid water while allowing moisture vapor to escape.
20K / 25K Rating
Inner Protective Layer
Lightweight tricot backing that protects the membrane from body oils and wear while improving next-to-skin comfort.
BreathFlow™ Lined
Lab Certified

All materials tested in our environmental simulation chamber under conditions ranging from -40°C to +50°C and 95% relative humidity.

How It Works

Precision at the Molecular Level

LONGPOWER lab testing waterproof performance with microscope and fabric samples

Microporous Barrier Technology

The StormShield™ membrane contains billions of microscopic pores per square centimeter — each smaller than a water droplet but larger than a water vapor molecule. This physical barrier means waterproofing that never washes out or degrades over time.

Directional Moisture Transport

BreathFlow™ channel architecture creates capillary pathways that actively pull moisture away from the skin toward the outer surface where it evaporates. The result: you stay dry from both outside and inside.

Seam-Level Engineering

Every seam is fully taped using heat-fused tape that matches the membrane's waterproof rating. Critical stress points receive double-taping. It's not enough to use waterproof fabric — we waterproof the entire construction.

Environmental Responsibility

Our DWR treatments are PFC-free. Our membranes are bluesign® approved. We believe that protecting the explorer shouldn't come at the cost of the environment they explore.
