What People Are Saying

Why Buy 1 When You Can Have 3

"Loved this so much that I bought three. These are so light that I pack three. I swap out two during the day while backpacking and I use one for camp and sleeping. I hate long sleeve but you can't even tell you are wearing long sleeve."

steve c.

Great Addition

"Just completed a 135-mile section hike on the AT and this was my main shirt for the entire hike. Very comfortable, lightweight, and cool. It was easy to rinse and re-wear on the trail, and I was surprised how fresh it actually stayed compared to some of my other articles of clothing."

Ken E.

Feather Light & Perfect Fit

"I used my hoodie this week in the California Sierra’s. It did not disappoint!

The hood keeps the sun off my neck and ears. Being so light it was like wearing nothing. Two thumbs up on this one!"

Damon

Great Fit & Performance!

"Compared to other brands with a similar fabric and design, the Altitude really shines for me in the fit as a next to skin layer. The hood is a good size and provides the right amount of coverage you'd want and need for protection from the sun on your ears and neck. The sleeves are a good length for me, and I've even got an almost +2" ape index."

Devin

FABULOUS Base Layer!

"The Altitude Performance Tee continues Outdoor Vitals "tradition" of coming up with innovative and useful gear! Purchased one (in black) and when I tried it on, knew I was going to get a couple more. Fit is great, unbelievably light weight, and comfortable--"

Mike

One of My Favorite Pieces of Clothing

"This garment is excellent for it's intended purpose. I use it exclusively for summer hiking (great sun/bug protection), and as a base layer in the shoulder season. Works like a charm for sun/bug protection and weighs next to nothing."

Zachary

Excellent Lightweight Piece of Gear

"This hoodie kept me cool, comfortable, and well protected on my 11 day adventure without the need to slather my whole upper body in sunscreen. I didn't see a single cloud during my entire trip and I didn't even get the slightest hint of a burn even up past 14,000 feet on Mt Whitney."

INNOVATIONS

FUZE™ Antimicrobial Treatment

FUZE is a treatment that leaves pure silver mineral permanently adhered to the fabric & doesn't wash out. This treatment eliminates germs & denatures them on contact. That results in a 95% smell reduction after 24 hours of wearing compared to non-treated fabrics.

FUZE does not use any surfactants of chemicals as binders. There are no harmful effects to mankind or the environment.

Quick Drying Moisture Management

The 80 GSM polyester fabrics used on the Altitude not only wick away moisture well, but dry incredibly quickly! The synthetic fabric is naturally hydrophobic - meaning that its fibers repel water rather than absorb it. This enables the fabric to dry very quickly after the weave of those fibers wicks moisture off your body or if you get wet from external factors.

Ultralight Weight

At just 4 oz, the Altitude may be the lightest weight sun hoodie we know of! Not only does it wick moisture & dry quickly, but the ultralight fabrics on the Altitude also BREATHE.

This is very important for use in high-exertion or high temperature activities. The lightweight & breathable fabric will protect your skin from the sun WITHOUT causing you to overheat. That kind of breathability gives you a piece of gear that you can use year-round, either as a winter base layer or summer sun shirt!

The Altitude was built for those that push further, climb higher, & don’t take no for an answer. Its near weightlessness & breathability combined with a thoughtful design will keep you comfortable whether you’re trail running, hiking, or in almost any other outdoor setting.

The name "Altitude" comes from the need to protect ourselves from some nasty sunburns, especially at high elevations. One of the significant tests we put the Altitude Sun Hoodie through was when we backpacked the Uinta Highline Trail, a trail the stretches over 100 miles with 80% of those miles above 10,000 ft! It performed exceptionally well, & we came to rely on the Altitude for adventures afterwards!

The Altitude Hoodie is perfect for high activity. No hardware. No frills. Just pure performance.
