Description

The Altitude Performance Tee is built for hot-weather movement, delivering ultralight comfort and breathability in a layer designed to keep you cool when it matters most. Made with 80 GSM fabric, it allows air to flow and moisture to escape quickly, helping regulate temperature during hiking, running, and high-output activity. The close-to-body fit improves performance without adding bulk, making it ideal for long days in warm conditions.

Designed as your primary base layer, the Altitude replaces a standard t-shirt with a more technical solution for heat, sweat, and movement. It dries quickly, resists odor with FUZE™ antimicrobial treatment, and layers easily when temperatures change. When staying cool and comfortable is the priority, this is the shirt you reach for.

Specs

  • Performance Benefits: breathable, fast drying, moisture wicking
  • Fit: Close - The Altitude should fit close to skin and fit easily beneath other layers.
  • Gender: Men's sizing
  • Warranty: Outdoor Vitals Performance Promise

Lighter & Cooler By Design

The Altitude Performance Tee is intentionally built with ultralight 80 GSM fabric to maximize airflow and comfort in hot conditions. This allows heat and moisture to escape quickly, keeping you cooler during high-output activity.

While it is not designed for heavy abrasion or bushwhacking, it performs exceptionally well for hiking, running, and backpacking where breathability and weight matter most.

Why This Isn't Just A T-Shirt

The Altitude Performance Tee is built specifically for outdoor performance. Unlike standard shirts, it uses ultralight fabric, advanced moisture management, and a close-to-body fit to improve airflow and reduce heat buildup during movement.

Stays Fresh Longer Than Other Synthetic Shirts

The Altitude Performance Tee 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.
