Sizing Notes
Measurements are stated in inches unless otherwise indicated. Size chart values represent body measurements, not garment measurements.
SHORT: Some pants are available in short sizes, which generally means an inseam that is 2.5 inches shorter than regular sizes.
TALL: Some pants, shirts, jackets and parkas are available in tall sizes, which generally means an inseam that is 3 inches longer and a rise that is 1 inch longer, a shirt or jacket body that is 2 inches longer, a parka body that is 2.5 inches longer and sleeves that are 2.5 inches longer than regular sizes.
Capri or cropped pants have an intentionally shorter inseam—reference the technical specs instead of this chart.

Runs a bit large
Great top for sweaty southern climates. Sizing seems to run a little large. I’m a small large or a large medium. I usually go large with most tops though. The large on me was like wearing a tent. So..if you’re a tweener, size down. Medium for me is a great fit.
Sadly Ineffective Wicking
The tank top was certainly lightweight when I put it on. I am 6'1" and 200 lbs and it was a little short on me but not too bad. Maybe could have benefitted from an extra inch of two in length. However, I am truly disappointed in its "moisture wicking" properties, which are key since I live in Texas and it is extremely hot. After an hour-long walk in the early morning (still relatively cool) the shirt was soaked and sticking to me like a wet paper towel. Not wicking, not quick drying, just soaked and clinging. My cheap Amazon tanks do better, and I was looking for an improvement over those.
Terrible moisture wicking
Agree with other reviews that this tank gets completely soaked, clings to the skin, feels heavy on you and wet, and is not quick drying. I’m comparing to other dry-fit tanks I own, that do not feel so soaked and heavy, nor do they cling to the skin. Besides that at least it looks good, fits nicely and is lightweight, but was hoping for those improved other features.
Perfect for Running
This tank top is almost impossibly light. It is the next best thing to going shirtless and provides wonderful air flow while doing really any physical activity. The shoulder straps are a good width and the fabric drapes in an aesthetically pleasing way.
Light, comfy and nicely large
Yes this is a larger fitting top but I am also a larger fit so this suits me. Worked really well on a hot summer run and tennis playing too. Easy to clean and doesn't stink like some dry fit shirts do. So light you forget you're wearing it.
Solid tank!
Super comfy!! I’m a woman, about 5’5” and 175-ish lbs. the medium fits how I like a tank top to fit (not tight; loose, but not swimming in it). Sometimes I just want a normal tank top with no weird cross cross back, flowy curved hem, and in a color other than pink and purple. And this tank delivered.
Too wide
Purchased the medium and it is really wide in the armpits. Much wider than a typical medium would run. Seems like a nice tank otherwise, but hand to return
Hot weather staple.
Great for hot humid weather. Light, breathes well, looser cut. Unfortunately only been able to fine 2 colors in my size. Ran 10 miles in 110% Mississippi humidity with no nipple chaffage.
weird boxy fit
The fit on this is way too wide for a running or even a workout tank. It’s also about an inch too short. I’m 5’11 180 lbs and in pretty good shape. The fabric is a nice and unique ultralight micro grid. Would be great in a tighter fit but the boxy fit combined with the ultralight gooey fabric reminds me of a moo moo. IGoing back to the store. If you have a sticky barrel chested build it might work but I worry would be too short
Runs extremely small or I got an abnormal item.
I've seen other reviews say this runs large. I either got an irregular item or this is patently false. I'm 6'3" 210lbs and wear a large in everything and have a few looser singlets that are medium and still fit. This fits like a men's small at best.
