Super Soft and Comfortable, Just Not the Most Forgiving Fit
Color: Purple, Size: X-Large
This top is incredibly soft and comfortable, which was the first thing I noticed. It has a really nice, lightweight feel that is easy to wear and not too thick or heavy, making it great for everyday use. Fit is true to size, but I would not call it very forgiving through the midsection. It is not cropped, but it also does not have much added length, so it hits in a way that can highlight the stomach area more than expected. Just something to be aware of depending on how you like your tops to fit. I know the material blend can pricey but still not sure I would say it's value is worth it. I like it, but I odn't love it. The purple color is better in person than the picture though! Overall, it is a great basic if you are looking for something soft and comfortable, just know it leans a bit more fitted than flowy.

Love the material, very comfortable
I got the black in a size small, and the fit turned out perfect. It’s relaxed enough to actually move in comfortably, and looks really nice for a plain athletic shirt. The fabric is super soft right out of the package, and the tagless construction and flat seams mean there’s nothing scratchy or irritating even after wearing it for hours.
The breathability and moisture wicking actually live up to its claims. It stays lightweight and cool in a way that cheaper workout tops just don’t, and the bamboo blend does seem to hold up surprisingly well on the odor resistance side of things too. The fabric is nice and stretchy while managing to not lose its shape as the day goes on, and so far the black has stayed vibrant through washing.
My only slight hesitation is the price. While not bad by any means, $20 for a single athletic t-shirt is a little more than I’d typically spend. Having worn it a few times though, I think the quality ended up justifying it.
Overall, if you’re looking for a workout top that actually delivers on its claims and holds up over time better than the cheaper versions, this one is worth the investment.

Great top for a heatwave
Color: Grey, Size: Large
We are in the midst of a heatwave in SoCal (95 degrees on St Patrick's Day, sheesh), and this tee really proved its claims today! I ordered it in gray, in anticipation of needing to deflect light, I just didn't think I'd need it this soon. At any rate, I love the coolmax plus bamboo plus vicose blend. I've learned to check the fabric of almost offering these days as somehow detestable synthetics (I won't say the P word, but it rhymes with Esther) because they trap heat, and the whole reason I'm buying summer clothing is to try to keep my body temperature on the cool side!
At any rate, this lovely blend did help keep me cool and dry, and the curved hem is really flattering. You might not think that such a small detail would make much difference, but I find myself reaching for this for that reason alone!
I ordered a Large, but likely shouldve gone with a Medium. It's a bit baggy but allows a lot of movement, so it's fine. I'm often between sizes and toss a coin pretty evenly split on which size I eventually settle on, so it literally is a real toss up. In the hope of helping someone else, I'm 5'5, about 145 lbs, 29 inch waist, and I wear a 34F/34DDD. I read another review that said that the shirt was too short, but I didn't find that to be true with mine. It fell to a flattering position, as in the photo, but maybe different colors have different sizing, as I've run into sometimes with major chains, and it's annoying. So take it with a grain of salt. I've already washed it and it doesn't shrink, nor did I expect it to.

Breathable and light
Color: White, Size: Small, Color: White, Size: Small
This shirt is truly better in person than in the stock photos. Its just a bit more of a textured athletic material in person that looks nicer on than a simple loose standard t shirt. The material does still sit semi loosely and only mildly hugs curves but its still figure complimenting and looks just a hair above only casual. Its very very breathable and lightweight, excellent for the gym or summer running etc but also serves as a phenomenal base layer for hiking and sports that carry into colder climates and seasons . Its well made and fots my size well so the size chart feels spot on. This shirt is really only losing points for me in the cost department because while its decent its nothing special. Its a good basic but its not something I couldnt find almost everywhere else.
