Lightweight Versatile Collared Running Shirt

[This review was collected as part of a promotion.] I am an active runner on all surfaces, boardwalk, pavement and trails. I have the deep mauve color which is a really nice shade. The shirt is lightweight and breathable, it was able to wick away the sweat even when wearing it under multiple layers, which could be attributed to the fabric and the vent in the back. It also was comfortable against my skin, no chafing. And there was a snap closure on the chest pocket, so it can hold your earbuds or a car key etc. Style-wise I felt comfortable going from a workout directly to a breakfast meeting for work since it’s a sharp collared shirt that doesn’t show sweat. Overall it is a very versatile shirt that I will get a lot of use out of.

Perfect breathable button up

[This review was collected as part of a promotion.] Love the color and that this is collared. Gives the shirt a lot of versatility when taking it out. This was the perfect shirt to take on an uphill hike. There’s openings in the back that allow for a ton of ventilation. Plus the material dries quickly too so if your prone to sweating a lot this is a good option to consider. Buttons hold together pretty well. The only complaint I have for this top is that if it is really windy like it was on my hike - the ventilation holes in the back allow for air to come into the entire shirt and make it so that the entire shirt “puffs” up. It makes your entire silhouette big but honestly I’ll take it because it’s roomy and cools you down. Overall looks good and feels good.

50 Mile Ultra Worthy

Great for a day of running in the mountains. Used this for first time on 50 mile ultra, was able to unbutton a few times to get a breeze, it fit ice bandana really well by opening up buttons, and it overall was really light and exactly what i was looking for.

The perfect active shirt

[This review was collected as part of a promotion.] The ACG Aireez trail running top is a great active shirt that also looks really nice too. It’s slimmer fitting with a longer sleeves for sun cover. The material is very comfortable, lightweight, and a little stretchy. It’s a very long shirt though so maybe best for a tucked in look. I would’ve liked it 2 inches shorter in overall length. Small fit 38” chest very well. The sleeves have good mobility for hiking or jogging. The vent in the back keeps the airflow going and avoids sweat build up. The snaps instead of buttons are fun to use too!

Comfy Lightweight Shirt

[This review was collected as part of a promotion.] Great shirt for fishing and hiking. The lightweight material is soft and comfortable and the air vents in the back make it a nice sun shirt with solid stitching and buttons. I’m 5’ 10” and 165 lbs and the medium fits really well with a slight taper. I wasn’t sure about the purple at first but it has grown on me.

I NEED MORE!

[This review was collected as part of a promotion.] Not often am I so impressed with a product that I have zero critiques, and this is one of those times. The ACG “Aireez” shirt has quickly become my go to for anything outdoors. From hiking to fishing to disc golf, this shirt checks all the boxes and does it all better than items made specifically for those activities. The shirt is true to its name, it almost feels like you’re wearing nothing at all, as if it was made of air. I’ve never had a shirt that breathes this well, not only does it have an opening on the back similar to fishing shirts, but the material is woven in a way that leaves air gaps all over the shirt. Not only does it perform well, but it looks good while doing it. Has a slim but comfortable fit, true to size. I’m 6’2 and about 190-200lbs and XL fits like a dream. The only problem is that I don’t have every color they make, I will be buying more! If this shirt holds up over time, durability wise, I would say that it’s the perfect outdoors shirt. We will have to see as I get some more use out of it.

ACG Button up

[This review was collected as part of a promotion.] Overall, great shirt for any outdoor activity related to nature. The lightweight but durable material was breathable and did not retain moisture. Slightly better fit for medium to skinny built, size up if you're on the heavier side. A++ product

Running Shirt Comfortable to Wear Anywhere!

[This review was collected as part of a promotion.] The ACG Aireez Button-Up shirt is one of the more versatile pieces I’ve worn from Nike. The material is extremely lightweight and breathable very comparable to Nike’s Dri-Fit quality. Especially during the changing seasons between summer to fall the shirts kept me comfortable during warmer days while not being too heavy. What stands out most is how many different settings this running apparel can be worn in. I’ve worn it in office in a business casual work setting, obviously for its intent in running but also just going out for something casual like sporting event or sports bar. One callout is the button up design can feel slightly oversized around the waste if untucked on slimmer builds such as myself. Would recommend order to your true size.

ACG Aireez

[This review was collected as part of a promotion.] What did you think about the fit and feel of this apparel item? I have never tried on one of these ACG shirts and I can honestly say I was amazed at how light this shirt is. It felt like I was holding a feather, extremely light and flexible. The fit was true to size and for those who like a true to size that outlines your physique, this is perfect! There were no weird fitting areas and no discomfort. Extremely impressive! What did you think about the design, did any features stand out? I was particularly intrigued by the cut out style in the back. I had never tried on a shirt that had this feature. After wearing it multiple times, I can say it’s a welcomed style because it makes the shirt extremely breathable. I typically “run hot” and I sweat easily, however with this shirt design, I was kept cool. The outdoor style of the shirt also makes it a unique design element, you can dress it down or up to meet the occasion. How did this apparel item perform? After wearing it multiple times at work and outside, the shirt performed spectacularly. It flexes to your movements, it never gets in the way, and it doesn’t feel intrusive. I love it when an apparel item feels like it’s a part of you, an extension to your body. This shirt did exactly that, I forgot I even had it on because it’s so light and feels so natural to wear. I can tell this shirt was built to last and perform well under any circumstance. I was not disappointed at all. I am blown away by its performance so far. What did you like most? What would you change? I liked the bold styling and the different layers. The snap on buttons are a game changer! They button up so fast compared to regular buttoned down shirts. The shirt is easy to wear with a solid tee below or buttoned up all the way. It’s very flexible to personal styles and has a catchy design. I wouldn’t change anything about this shirt, it’s exactly up my alley. I’m extremely happy with what this shirt has to offer.
