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.

Almost Perfect

This sun hoodie is overall amazing, it performs very well in hot environment and is perfect if your on a trail with no shade. If I could change one thing it would be to make the torso length about 2 inches longer, right now it kind of rides just below your belt line and is a little too short. I love the hood on this, it stays in place and doesn’t affect your peripheral vision. This is the best sun hoodie ever designed, add two inches to the torso length and it is perfect.

A little short in the arms and torso...

Excellent hoodie. It's designed for shorter wider hikers. Either a tall version with a couple inches added to the sleeves and torso or just a little extra length for the 6' ,140lb. Hikers out there. Besides that, excellent! I'll try the medium size next purchase.

Perfect for summer camping, hiking and backpackin activities

The Altitude Sun Hoodie is ultra-lite weight (~ 4 oz for size XL on my digital scale). It works as a hoodie for sun protection when hiking and backpacking on sunny / cloudy days. It also functions as a comfortable baselayer to sleep in at night if and when the temps drop. Its light weight and dual functionality is the trifecta for my backpacking gear.

Love it but just know..snags

Love the hoodie! Very comfortable and the hoodie portion is awesome for sun protection on my neck and head without overheating. But beware of tall brush. I hike in SoCal and many places have tall brush. You will get snags but this doesn’t reduce the effectiveness on the overall performance. I’m very happy with the product. It’s keeps me cool and protected. It's my #1.
