Blazing sun, miles to run. Nike made this top with UV protection and a collar you can pop for extra coverage. The vent in the back helps with airflow and lightweight, stretchy taffeta moves sweat.

[This review was collected as part of a promotion.] The Nike ACG Aireez T-shirt features built-in UV sun protection and has a back vent opening for improved airflow, making it a good pick for warm days for outdoor walkers or runners who spend a lot of time in the sun during spring or summer. Made from a blend of 72% nylon and 28% spandex fabric, it provides a cozy feel, plus stretch during hikes, runs, or other activities. However, I found the shirt to be slightly sheer, smaller than expected, and priced higher than it should be. I’ve come to expect better quality materials from ACG products. Overall, the Nike ACG Aireez is a slightly overpriced, comfortable long-sleeve shirt suitable for those warm, sunny days.
[This review was collected as part of a promotion.] I really like this shirt! It looks and fits really well. The material is lightweight and feels comfortable, which is perfect for Florida weather. I also love the color because it looks nice and goes well with different shorts or pants. The shirt has a casual but stylish look, so it can be worn for hiking, traveling, or just going out. I also like that it has long sleeves for extra sun protection. Overall, it’s a really nice and practical shirt, and I am very happy with it!
[This review was collected as part of a promotion.] I've used the ACG "Aireez" Long Sleeve Button-Up for two actives: hiking and trail running. Its lightweight design and built-in ventilation help keep me cool during warm Los Angeles evenings. When trail running, I appreciate how breathable and lightweight the shirt feels and the UV protective fabric gives me added peace of mind when spending long periods outdoors. One downside I noticed is that despite being designed for warm weather activities, the fabric tend to cling to my body once i start sweating, which can get a little annoying during more intense runs. Overall, i think this shirt is ideal for hiking, especially as a light weigh base layer. I enjoyed wearing it on the trails because it provides sun protection without feeling bulky or adding unnecessary weight. While the fabric could handle sweat better, its still a solid option for outdoor adventures in warmer weather.
[This review was collected as part of a promotion.] This button up is so breathable I feel like I’m wearing nothing at all. It’s also comfortable and is slimming. The buttons are easy to put on and are secure enough for me not to worry about them coming apart. The khaki colorway is a nice change for me. It makes me feel like an explorer. I sweat in it but it doesn’t build up around the arm pits. At least it doesn’t show. The shirt drys so fast that my sweating is unnoticeable. The open flap in the back lets my back sweat dry quickly on short breaks.
[This review was collected as part of a promotion.] Tailored fit and incredibly lightweight. Perfect for staying covered up on sunny days without any heaviness. Think of situations when you want more than a t-shirt, but less than a jacket. I really appreciate the back vents for breathability. This button-up is definitely a very interesting concept for running, trails, etc.
[This review was collected as part of a promotion.] I wore this shirt over a tee while traveling and hiking in mid to low 60F in daylight. I found it to keep me at a comfortable temperature and I tend to run hot. I like but don't love the look and it can get very wrinkled.
[This review was collected as part of a promotion.] I’ve been wearing the ACG Long-Sleeve Button-Up Trail Running shirt for a couple weeks now and have really enjoyed it. The material is thin so I have treated it as an extra layer on hikes, which also makes it super easy to pack. It breathes really well and the snap buttons make it really easy to put on or take off while you’re on the move. The look is relaxed and goes with any bottoms. I wore it on several hikes out west recently and wish it provided a little more protection from the cold, but it was still a good piece to have. Glad to have this for future use.
[This review was collected as part of a promotion.] This is a great lightweight piece for hikes that start off cool but heat up. Vented backs for cooling airflow. Snap front buttons add lightness. Love the color and fit. It styles pretty well
[This review was collected as part of a promotion.] What did you think about the fit and feel of this apparel item? -The ACG "Aireez" Men's Long-Sleeve Button-Up Trail Running Top felt great due to the thin material the breeze came through easily and made me feel comfortable. The material has a way of showing your physique which is a plus for athletes and models. What did you think about the design, did any features stand out? -ACG "Aireez" Men's Long-Sleeve Button-Up Trail Running Top stands out due to the light tan color and the way the shirt will show body shape. This is a shirt that could be worn in the gym, while running or a casual occasion. How did this apparel item perform? -ACG "Aireez" Men's Long-Sleeve Button-Up Trail Running Top performance was great for the usage after working out. The material of the shirt shows good body shape. Also the shirt looked good and matched the outfit by surprise. What did you like most? What would you change? -What I liked the most about the shirt is the button up and the way the shirt shows body features. If I could change anything I would want more colors to test the appearance.
[This review was collected as part of a promotion.] The ACG long-sleeve button-up has a great balance of comfort, functionality, and style. The fit is true to size, with a relaxed feel that isn’t overly baggy and still complements your natural shape. The material is incredibly thin, soft, and breathable, making it a great option for hiking, outdoor activities, or everyday casual wear. One feature I appreciate is the ventilation openings along the back, which allow for additional airflow when you’re active. However, the openings are completely exposed, and I think adding a lightweight mesh liner could improve the design without sacrificing breathability. Alternatively, this shirt could work really well as an overshirt layered over a lightweight tee. Overall, it’s a comfortable, versatile piece that delivers on breathability and looks great while doing it.
