Altitude Performance Tee

The Altitude Performance Tee is the perfect base layer. Whether its short sleeve, long sleeve, or hoody.
I've worn Performance Tees on extended packs in the Wind River Mountains and on Wilderness Hunting trips. They wick moisture, do not smell after multiple days of use and are the most comfortable base layer I've ever worn.

Bought the long sleeve tee looking for a good base layer and I was not disappointed. Wore it almost every day. Temps from 32 to 75 and I was comfortable the entire time. I really like the fit. And it worked as advertised, keeping me dry on warmer days as well as cold nights. I will be buying some more before my next trek.

My wife and I both loved our new Altitude Sun shirts. We both wore them on our recent trip to Germany. Super light weight and packable. Very comfortable with a great fit. Only minimal issue was prone to snag. Also pictured is our OV puffy jackets from the first Kickstarter. Thanks for great products.

Just used it on my hike to Mount Langley in California. The shirt performance was exceptional!
Regulated my body temp and kept me comfortable.

Love my Altitude Hoodie and this shirt is just as great. I use it on days I want some coverage but don't need the coverage. It is super comfortable and barely feels like you are wearing anything.

I have the sun hoodie, fits great and lightweight.

Lived up to my expectations as always

Amazing product. I have used similar products from other top brands, but nothing as lightweight with the same level of performance. I now have several in different colors and prefer them over hoodies for most outings. However, the performance hoodie is a must for hot sunny days for sun protection. My only wish is that there was a version with a larger Outdoor Vitals logo across the chest and back as we are proud users of our gear.

I got my altitude sun hoodie free with my membership. Turns out I hate hoodies, since I think I keep cooler and get better sun protection with a light wide brimmed hat and a long sleeve. Enter the Altitude long sleeve Tee. This thing is amazingly light, cool, and quick to dry. (I cut the hood off my hoodie and used it to make a light mesh to replace the top of my broad brimmed hat - way better than the Sunday Aftertnoons Ultra Adventure or OR Sunrunner.) The Altitude is frays easily and is somewhat fragile, so I'll wear my MH Crater Lake when bushwhacking, but the Crater Lake - one of the better sunshirts - doesn't come close to keeping me as cool or dry as the Altitude, Lastly, although the Altitude doesn't have an SPF rating, I've worn it for many hours in the sun, and never felt like I got any sifnificant UV exposure. For warm and or active conditions, the Altitude really delivers. I know I'll have to replace it more than the Crater Lake, but that's a price I'm willing to pay.

This is a super comfortable performance tee! Really light weight. This is my second version, I also have the hoodie version. Great quality as always.

Great sun protection for the hot AZ desert. Very cooling for a long sleeve shirt. I love it and will be getting more.

I love the fit and lightness of this shirt. Can be worn as moisture wicking base layer or as sun protection. Great for Hikes and Runs. Very Lightweight.

This is the third altitude performance shirt I own. I already had two long sleeve ones. This is my first short sleeve. I wear these shirts at work all the time under my work shirt as well as on the trail. They are awesome.

Really pleased with the fit and lightness of my new shirt. Serves as a lightweight base layer for cooler weather and great sun protection when it's warmer. I find myself putting it on frequently.

Love my long sleeve altitude tee. Very versatile whether on a hike, at the gym or chilling around the house.

Great fit, love the breathability in the fabric.

I bought the performance tee along with the performance hoodie. I have worn them together to provide a touch more warmth on these chilly mornings. Then after awhile, I can shed one has I get hot from walking. While they aren't officially a base layer, I can wear it that way.

Feels great on my skin

It’s amazing, it fits incredibly well, super breathable and a must have for any intense activity or hot day

I've added this shirt to my collection of OV gear i use for hiking. Same reliable performance that I am used to and I'm very happy with my purchase.

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.

This is the best shirt I have owned. It is very light weight and fits perfect.

Wore this T-shirt in the hot August humidity of Florida. Perfect T-shirt for that climate.

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.

The fabric is as light, soft, and breathable as everyone says. The grid pattern also looks quite striking. The fit specifically of the sleeves is quite slim - I'm a tall lanky guy 6' 2" 160lbs and if my forearms were any larger this would be squeezing too much. My main gripe is the stitching of the sleeves seems quite sloppy and after just 2 wears it is coming undone and fraying.

These shirts are the best for hiking, Ultra Marathons and look so cool too. The material is so comfortable. I have bought some more of them.

I haven’t been able to get this out in the field yet so, I can’t speak to the durability of it especially when going through brush, but so far it has been great for just being outside. It is way lighter weight than other sun shirts I have and breathes pretty well. Just cause I haven’t actually put it through its paces is why I can’t give it 5 stars but so far I would recommend it.

Super nice lightweight shirt.
