Altitude Sun Hoodie

The Altitude Sun Hoodie was built for pushing boundaries and conquering new heights. Designed for those who seek adventure and demand performance, the Altitude is one of the lightest weight synthetic sun hoodies available. Here's why it's perfect for your next excursion:

  • Near Weightlessness and Breathability: Experience unparalleled comfort with the Altitude's lightweight construction and exceptional breathability. Whether you're trail running, hiking, or exploring the great outdoors, its thoughtful design ensures you stay comfortable every step of the way.
  • Sun Protection: Named for its ability to shield you from the harsh sun at high elevation, the Altitude Sun Hoodie is your defense against sunburns. Tested on the challenging Uinta Highline Trail, it proved its worth over 100 miles of rugged terrain, with 80% of those miles above 10,000 ft in elevation.
  • Moisture Management: Stay dry and comfortable no matter the conditions. The performance synthetic fabric wicks moisture away from your skin and dries rapidly, making the Altitude suitable for year-round use as a base layer.
  • Comfortable Fit: Designed for high activity, the Altitude offers an athletic fit that's not tight or restrictive. This allows the synthetic blend to effectively manage moisture while providing freedom of movement.
  • More Coverage: The high collar offers maximum coverage, even when the hood is down. The ultralight fabric provides sun protection without causing overheating, so you can adventure day-in and day-out without worrying about sensitive skin. 

Experience better back country comfort with the Altitude Sun Hoodie. No hardware, no frills—just 4 oz of breathable & protective performance.

Altitude Sun Hoodie

Fantastic product. I love the overall fit, especially the slight amount of extra torso length. This keeps the shirt from riding up my hips behind my pack. As advertised, the hoodie is extremely lightweight!


I use it for work. The light but tough fabric makes it great for working hard in the sun.
Make sure you pay attention to the warnings about Velcro… it’ll ruin the shirt if you’re not careful.

The Only One I’ll Wear!

I’m in love with my Altitude Sun Hoodie! After wasting my money on others, and still feeling overheated in the sun, and chilled in the shade, I took a chance on this sun hoodie, and I am so glad I did. I don’t overheat in this one, and I don’t get chilled in the shade. It lets all the sweat evaporate, and dries so quickly. The real miracle is that I and the hoodie don’t stink! Seriously, I’ve use it for 6 hikes and haven’t washed it! I can’t do that with my other hoodies. I don’t miss not having thumbholes; never used them on my other hoodies anyway. The tight fit is different, and I like it - it shows me instantly that I need to get my dad bod under control! LOL! I will definitely be buying more!

Super UL- I ordered the wrong size

I fully agree it’s a great product and I plan to order another one a size larger for myself. I gifted the one I received to a friend because I didn’t want to hassle with the return procedure. I know my friend will enjoy and I look forward to hearing his feedback, we adventure quite often together.
