REI Co-op  Swiftland Grid Running Tank Top - Men's

Overall, the product performed well on my recent hot, humid, and hot, normal humidity runs. The fabric wicks away moisture well, feels light and breathes well. On one of my longer runs, the moisture evaporated quickly and did not leave a soaking wet feeling when used. The shoulders have enough coverage for my running vest, but not wide enough to use on really long runs due to chafing, as it would not cover as much on the back. When used as intended, it works well. It is more loose-fitting and not an athletic fit. The fabric feels light and is perfect for the warmer months or even race day.

I wasn’t crazy about the camo-ish look at first glance, as I usually prefer bright colors for visibility. However, this green palette looks sharp when paired with the forest green Swiftland shorts. As to fit, this is great. It’s extremely lightweight, breathes really well, and does a great job wicking away moisture for me as a copious sweater when I run. The material doesn’t cling either, which helps with the airflow. For the heat and humidity of a Southern summer, this tank top is a great choice.

Very nice tank top. Perfect for running. The design is very great in my opinion. I like the colors and the texture. The tank top is very light and barely noticeable which is great for long run. Easy to clean and dry extremely quickly. The only negative point is that I preferred a medium and it might be a bit large. So something to consider

Recreational runner here, typically average about 50 miles per month. Fabric - very light to the touch and airy, great temperature control for warm days and runs, fabric allows for an easy breeze Fit - I would true to size for a medium and has a more "standard" fit over a "slim," which helps with heat management, but isn't too baggy/bulky to be flapping around or annoying Quick dry - I tend to sweat pretty heavily with runs, but this tank did a great job of drying off quickly just sitting outside at a cafe for a coffee, never had a heavy/damp feeling Color - green is super vibrant but the pattern is a little weirdly joined together, small nitpick and totally subjective, so while I found it "meh," it doesn't really deduct from the overall use or performance of the tank Overall - has become one of my favorite running tanks that I also use for more sweaty workouts

I wore the REI Co-op Men's Swiftland Grid Running Tank at Trinidad Carnival, and it was hands down the perfect choice! From the moment I put it on, I could tell it was built for movement. The lightweight, breathable fabric kept me cool and dry through the heat, the crowds, and hours of non-stop dancing. Even under the blazing Caribbean sun, the sweat-wicking material did its job—no sticky discomfort, just pure comfort. The fit? Spot on. Snug but not restrictive, it let me move freely while I jumped, danced, and fully embraced the soca energy. No chafing, no irritation—just soft, comfortable fabric that felt great all day long. Plus, the sleek, modern design fit right in with the Carnival vibe, and I even got a few compliments along the way. What really impressed me was how well it handled the heat. Even in the hottest part of the day, I stayed cool, and when the party stretched into the night, the reflective accents were a nice touch. This tank has definitely earned a top spot in my activewear lineup. Whether you're hitting the road for a run or dancing till sunrise at Carnival, it delivers on both style and performance. Highly recommend!

I would avoid this tank for any active pursuits. It is great at absorbing sweat but horrible at letting it evaporate. Never before have I had a shirt that needed to be taken off mid-run to wring out. The cut is insanely baggy around the stomach; I usually wear a large but the medium feels like a dress. All this contributes to feeling like I'm wearing a plastic bag while running.

Extremely lightweight and packable. Fits well, either as a sole layer or an underlay. I tend to use it more as an underlay only because in practice I'm not terribly fond of the print — too busy. But in some other neutral color, black, etc. this would easily be a running shirt in hotter weather.

This tank top is simply too long. It's even longer than seen in the picture because it's longer in the back than in the front. I wear tank tops for work outs in the gym and I hate the feeling of sitting down on the shirt when I do any kind of a seated exercise. I'm returning or discarding.

I like the fabric used. It feels like a quality tech fabric. However the fit of the neck opening is weird. The neck looks normal on the model. But in real life it is like a boat neck in the back. I like a tank that scoops in the front and not in the back.

I bought this a few weeks ago for an upcoming race this summer. I love the breathability and light weight. This top is best for warm weather. If you’re running in cold/cool temps, you will be pretty chilly.
