Alpine Jersey

Black, Extra large

$92

The most versatile alpine layer in existence.

There's a reason it's called the Alpine Jersey.

If the high alpine had a team, this would be the uniform.

If the high alpine had coaches, they'd tell you to bring a shell.

They're probably right.

But underneath it, we'd still wear this.

We started with the Net Mesh Beanie and always knew this fabric deserved a bigger job. There are base layers and there are shells, but the space in between has somehow become crowded with pieces that work best when you're standing around. Or worse, pieces designed for movement that fit like they were made for a European cycling team instead of scrambling over loose rock.

We wanted something for movement.

Designed in Denver, Colorado. Tested in the Rockies. Built in Colorado from USA-made materials.

The Alpine Jersey is built for cold starts, long climbs, blown forecast reads, shifting weather, and those final miles back to the trailhead when the temperature drops and the thought of a burger hitting your sunburnt lips is the only thing keeping your legs moving.

Constructed from USA-made Polartec® Delta Net Mesh and fully built in Colorado, it regulates temperature across a huge range of conditions while remaining exceptionally breathable, quick drying, and easy to layer. The open mesh construction creates space between the fabric and skin, improving airflow and reducing cling during high-output efforts.

Wear it on its own. Throw a shell over it. Stuff it into the bottom of your pack and forget about it until you need it.

You will.

Fabric Technology

This beanie is constructed from Polartec® Power Dry™ Net Mesh, a performance fabric engineered to regulate temperature through airflow and moisture transfer rather than static insulation.

The open mesh structure creates continuous air channels that allow heat and moisture vapor to move away from the skin as output increases. Hydrophobic fibers limit moisture absorption, preventing saturation and maintaining consistent performance during sustained activity.

Unlike closed-knit or fleece fabrics, this system retains only the warmth necessary to remain functional while allowing excess heat to escape. The result is stable thermal regulation across changing effort levels and conditions.

Fabric System

Open net mesh. Airflow, moisture transfer, necessary warmth.

SIZING AND FIT

Small/Medium
Large
Extra Large

Model (Zay) is 6' 155lbs

The overall fit is boxy and cropped. The Small/Medium and Large have similar lengths but the Large has more noticeable room in the chest and shoulders. The major length jump is in the Extra Large. Many wearers can find comfort in multiple sizes and should pick best fit based on preference. Please note that the small/medium will come tagged as medium.
