Brooks Running Tank: Comfortable Fit with a Relaxed Feel
The Brooks Atmosphere running singlet is a solid choice for comfort, but its design leans more toward a training tank than a traditional running singlet due to the deep cut of the arm holes. The free-flowing style around the underarms allows for great breathability and unrestricted movement. One of the standout features is the soft, well-constructed seams, which minimize rubbing and enhance overall comfort during long runs. If you're looking for a relaxed fit with a bit more coverage, this tank is a great option that still performs on race day.

Men’s Atmosphere Singlet 3.0
The Men’s Atmosphere Singlet 3.0 is the best training top I have found in years and is my new favorite training top. The fit is true to size and hugs in all the right places without feeling undersized or tight.
The design is the best I’ve seen from any company. The cut under the armpit is low enough to prevent motion restriction ,but isn’t too low to make me feel exposed. The top straps are a perfect width, showing the just right amount of chest and shoulder muscularity without making me feel completely exposed or indecent.
The fabric is extremely comfortable. It drys quickly and doesn’t feel itchy when dry or wet. It is light, yet durable. It is breathable and keeps the body cool.
My favorite thing about the Men’s Atmosphere Singlet 3.0 is the design, specifically the cutoff and top straps. The designed compliments the uppers body muscles while maintaining a healthy amount of modesty.

Lightweight and comfortable
I’m starting my journey back towards getting into shape again. Having good gear always seems to help my mindset. I’m not a fan of tanks typically since they seem to show a lot of my sides, and while I’m 240 and not in shape, I don’t like showing them off. The singlet (2XL) however fits great and has a flattering cut. My running has been limited to a treadmill in a gym but the singlet feels great in use as well as to and from the gym. I’m actually excited to use it this spring running outdoors.
It’s a great fit and feel, I will definitely add more to my wardrobe.

Perfect Singlet for Running – Lightweight, Breathable, and Comfortable
I can’t say enough good things about this Brooks men’s singlet! From the moment I put it on, I could tell it was designed with runners in mind. The fit is incredibly comfortable, with a smooth, lightweight fabric that feels almost weightless while running.
One of my favorite features is the wide armholes, which eliminate any risk of uncomfortable friction under the arms—no chafing, just complete freedom of movement. I was initially concerned about the higher crew neck, thinking it might feel tight or distracting, but once I started running, I completely forgot it was even there. It fits so well that it almost feels like wearing nothing at all.
The breathability is also outstanding. At first glance, I thought the side panels were mesh and worried about transparency, but the fabric is fully opaque while still delivering incredible ventilation. It keeps me cool and dry, even on hot runs.
Finally, the bright blue color is a winner—bold, vibrant, and stylish. This singlet checks every box for a perfect running top, and I’ll definitely be getting more. Highly recommend!

Excellent comfort and performance
I recently purchased this running shirt, and it has exceeded my expectations. The fabric is lightweight, breathable, and keeps me cool and dry even on long runs. The fit is perfect—not too tight, not too loose—allowing for a full range of motion without any chafing. Plus, it holds up well after multiple washes without losing its shape or softness. If you’re looking for a comfortable, high-quality running shirt, this one is definitely worth the purchase!

Atmosphere Singlet 3.0, new favorite running top
The Men’s Atmosphere Singlet 3.0 has been an excellent addition to my workout wardrobe. The extremely light weight and breathable fabric gives this tank a relaxed fit that is overall a comfortable top. The design makes the singlet perfect for running, biking and general workouts- with the perfect amount of coverage over the shoulders but provides wide openings for under the arms and across the back. The fabric is quick to dry from sweat and is odor resistant, which is an absolute must have for long runs.
The vibrant color of the neon blue Atmosphere Singlet 3.0 makes this workout top a great outdoor run option, when so many of my typical workout clothing consists of black. Favorite aspect of this singlet is the breathable and comfort of the material!

Great shirt for very hot weather
Trying this shirt while running on a treadmill indoors, I found it to be very breathable. It's January right now, so I will not be wearing it outside to run, but it works great for indoors for now. When it gets warmer outside I will use it to layer, and it would work great by itself in very humid weather. This shirt will definitely be in my rotation from now on because of its breathability and ease of motion while moving in it. I will definitely check out any other shirts they have, as I think a long sleeve version would be great for my rotation too.

favorite new work tank
I am absolutely obsessed with this singlet! It is fantastic for working out and is absolutely my new go-to workout tank top.
To start with, it runs true to size (always appreciated), in my opinion, and fits the body well, hanging as it should in all the right places to keep me feeling stylish enough to wear for any casual occasion. The color (blue) is lovely as well.
The fabric is fantastic and feels lovely against the skin. It is made with moisture wicking material, which is very effective at keeping me cool while exercising. It also never stinks, even after an intense workout where I sweat significantly.
Overall, I'm a really huge fan of this singlet and look forward to getting a few more as this has quickly become a staple in my workout clothing rotation.

Comfortable, breathable, and lightweight
Absolutely love this workout top. It’s lightweight and breathable, but doesn’t feel cheap or flimsy. I’m usually between a size L and XL and went with this XL because I like having some breathing room in my workout gear. The XL was the perfect size for me. I’ve worn this for running, strength training, and playing basketball with friends and it worked perfectly for everything. I love that it’s so versatile.

Lightweight & Chaf-Free
Worn this a few times to the gym as temperatures are below zero here. Material is breathable and doesn’t cause any irritation on my skin regardless of amount of sweat. Fit was true to size and the cut fit me well in a size medium (5’ 10” and 160lbs).
