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 a women specific 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.

FUZE Antimicrobial Treatment

The polyester fabric used for the Altitude is literally lined with Silver. No, really. Silver mineral naturally kills bacteria & has been used in antibacterial ointments for years. FUZE™ has developed a method to permanently bond Silver mineral to fabrics to increase bacteria resistance & improve odor control. 

Now you get a 4 oz synthetic sun hoodie that not only wicks moisture & dries quickly, but ALSO kills bacteria & prevents odor buildup!

When bacteria come in contact with the silver mineral that has been permanently bonded to the fabric, the silver pierces their membrane shell - killing the bacteria.

Wanted to be happy

I was looking forward to wearing this hoodie a lot during my runs. I was extremely disappointed to find that after one wearing I came away with all these snags! I admit I did not read the 'fine print' about warranty but didn't think this fabric would be so delicate when rubbed up against other fabric (had a light jacket on). Maybe the sizing was too large for me and there was too much movement. I didn't return for exchange because the customer service messages I received when asking about this issue sounded like I couldn't . I am assuming any rubbing (jacket, backpack straps, etc) would do this.
Wanted to be happy, but just am not!

One of my favorite pieces of gear!

These sun hoodies are incredibly lightweight and quick-drying. As someone who works and plays outside much of the summer and HATES applying sunscreen, I basically live in sun shirts. I had been wearing shirts from Outdoor Research that were basically the same material; I was thrilled when I tried the Outdoor Vitals Altitude and found that it is just as comfortable and functional as the ones I had, while it also A) is less expensive, and B) has a more form-flattering women's fit. I've never been disappointed with an OV piece of clothing, and the Altitude is no exception!

Love this top!

I received the Altitude Sun Hoodie as a Christmas gift. It is extremely lightweight and soft. Its lightweight and comfortable features make it an excellent option for a base layer for running on chilly days. It is also a great choice as a single layer for mild temperatures. I'm looking forward to testing it out during the summer heat but I have a feeling, I won't be disappointed. I'll be buying this in more colors.
