Description

The Altitude Hoodie is built for high-output movement in hot, exposed conditions, delivering ultralight sun protection without trapping heat. At around 4 oz, the breathable 80 GSM fabric allows air to flow and moisture to escape, helping you stay cooler than a traditional t-shirt while still protecting your skin from direct sun exposure. Whether you're hiking, running, or moving through alpine terrain, this is the layer designed to keep you comfortable when temperatures rise.

Designed as your primary base layer, the Altitude replaces a standard shirt with a more technical solution for sun, sweat, and long days outside. It dries quickly, resists odor with FUZE™ antimicrobial treatment, and layers easily under wind or insulation when conditions change. When staying cool matters as much as staying protected, this is the piece you reach for.

What Makes The Altitude Different?

How The Altitude Holds Up

What Makes The Altitude Different?

The Altitude Hoodie is built specifically for backcountry performance, not casual wear. Every detail — from the ultralight 80 GSM fabric to the athletic fit and moisture management — is designed for high-output activity where comfort and efficiency matter.

Compared to standard sun hoodies, it is lighter, more breathable, and dries faster, making it a better choice for backpacking, alpine travel, and long days on the trail.

Stay Fresh Longer Than Other Synthetic Hoodies

The Altitude Hoodie uses FUZE™ antimicrobial technology, which bonds nano-silver directly to the fabric fibers to help reduce odor-causing bacteria. This allows you to wear it longer between washes compared to standard synthetic shirts.

While no synthetic fabric is completely odor-proof, the Altitude is designed to stay fresher longer on multi-day trips where washing isn’t an option.

How The Altitude Holds Up

The Altitude Hoodie is intentionally built with ultralight fabric to maximize breathability and comfort during high-output activity. While it is not designed for heavy abrasion or bushwhacking, it performs exceptionally well for hiking, backpacking, running, and long-distance travel.

For most users, this becomes the layer you wear the most — because it stays comfortable when other layers don’t.
