The Altitude Tee was engineered for those who demand performance and refuse to settle.  Near weightlessness & excellent breathability combined with a thoughtful design will keep you comfortable whether you’re trail running, hiking, at the gym, or in almost any other performance oriented setting:

  • Ultralight and Breathable: Designed for year-round use, the Altitude Tee offers near weightlessness and exceptional breathability. Whether you're tackling hot summer hikes or braving freezing winter expeditions, the 2 - 3 oz base layer will allow you to breathe & stay comfortable.
  • Moisture Management: Stay dry and comfortable no matter the conditions. The performance synthetic fabric wicks moisture away from your skin and dries rapidly, ensuring you stay cool and dry during high-intensity activities.
  • Athletic Fit: Enjoy a comfortable yet athletic fit that's not tight or restrictive. This allows the synthetic blend to effectively manage moisture while providing freedom of movement for any performance-oriented setting.
  • Simple & Comfortable: With no hardware, the Altitude Tee offers simplicity and decreased weight, allowing you to focus on your performance without distractions.
  • Sun Protection: Prevent sunburns with the long sleeve option without sacrificing weight or breathability. Stay both cool & protected during adventures.

Experience pure performance with the Altitude Tee. No frills, just reliable comfort and functionality for your most demanding adventures.

Soft and comfortable

Love this top. It is very soft on the skin and cool, especially if there is a light breeze. A men’s XS fits perfectly with just the right amount of looseness. I am female 5’8” and 110 #. I don’t like tight fitting clothes. My husband has the hoody and have the LS Tee to me as a gift. Look forward to getting a hoody too.

Altitude Performance Tee Meets the Specs

Worn the Altitude Performance Tee (short sleeve) once. It was very light and comfortable. Maybe should have purchased a long sleeve. Will be able to see how it works when I hike in Yellowstone National Park for 5 days.
