The ALPHIELD utilizes a proprietary three-layer shell with a mechanical stretch face fabric. To maintain the DWR finish, machine wash cold with technical detergent and tumble dry on low heat to reactivate the water-repellent coating. Do not use softeners.

We ship worldwide via carbon-neutral logistics. If the ALPHIELD doesn't meet your performance standards during your first expedition, return it within 45 days for a full refund or exchange.

The ALPHIELD: Engineering the silent performer.

We built the ALPHIELD because we were tired of choosing between technical performance and aesthetic intent. Most shells shout their presence with loud branding and crinkly fabrics. We chose a different path: silent, stretchy, and ruthlessly effective.

Unseen Protection

Beneath the matte finish lies a 20,000mm waterproof membrane that blocks driving rain while venting internal heat during high-output climbs.

Movement Defined

Articulated sleeves and mechanical stretch mean the ALPHIELD moves with you, not against you, whether you are reaching for a hold or a coffee.

The Resale Factor

Timeless construction ensures this isn't fast fashion. Our pieces hold 60% of their value because they are built to outlast seasons.

Designed for those who view gear as an extension of their identity.

Precision Cut

The tailoring on the ALPHIELD is unlike any other tech shell. It lacks the typical 'garbage bag' fit, yet I can still layer a fleece underneath comfortably.

- Elena V.

Truly Breathable

I wore this for a 40-hour push in the Cascades. No internal condensation, and it stayed dry through a 4-hour drizzle. Highly recommended.

- David K.

The Daily Driver

It's my mountain shell and my rainy day city jacket. The matte finish doesn't scream 'hiker,' which I appreciate for office days.

- Sarah J.

Rugged Build

I scraped this against granite chimneys all weekend. Not a single snag or tear. The durability is legitimate for serious climbers.

ENGINEERING SPECS

The Layering System

ALPHIELD is designed as the 'Shell' in our three-tier system. It fits perfectly over our base layers and mid-weight insulation without restrictive bulk.

AEROTREK Technology

Our AEROTREK membrane uses electrospun fibers to create a porous structure that allows air molecules to pass while blocking liquid water.

Sustainability Standards

We utilize recycled nylon and PFC-free DWR coatings to minimize our footprint on the landscapes we love to explore.
