A great shirt for me to wear to work
Size: Medium, Color: Navy, Size: Medium, Color: Navy
I ordered this shirt to wear to work because I’m pretty active at my job and need to move around comfortable. I’m 5’0 and around 115lbs, but people with the same measurements can have different body types - however I will say that the shirt fit me very well, had a loose fit, but not too loose, just comfortable and easy to move around while wearing. I wouldn’t say it did anything different in warm temperatures than any other shirt I own, but at least it don’t make me hotter. The fabric feels nice and good quality. After a handful of washes, the color still looks great so I have hopes that it won’t fade and look worn right away. It honestly looks exactly like the pictures. The majority of clothing items I’ve ordered off Amazon had left me very disappointed, so this was a very pleasant surprise!

Soft, comfortable, more of a casual tee than performance
Size: Medium, Color: Navy
This is a really comfortable shirt. The fabric is soft right away and it fits well without feeling tight or awkward. It drapes nicely and just feels easy to wear.
I wouldn’t really call it a true moisture-wicking workout shirt though. It feels more like a soft cotton tee than anything performance-focused. I haven’t worn it for anything super active, but based on the material it doesn’t seem like that’s really what it’s best for.
That said, for casual wear, travel, or light activity it’s great. Comfortable, breathable enough, and the graphic is a nice touch without being over the top.
Overall, I like it. Just go in expecting a comfy everyday shirt, not a high-performance athletic one.

Worn, lived in feel
Size: Medium, Color: Navy
The material is soft and breathable, with limited stretch but has a comfy worn feel. The fit is loose with a boxy straight cut, and hem that falls on or just above hip. The color is as seen in the pictures; a deep navy blue with logo print on the upper chest. It’s an everyday anytime kind of t-shirt. Looks great with leggings, jeans, shorts, etc.

Comfortable and cool. Does not ride up.
Color: 01-multicolour (4-pack), Size: Medium
Extremely comfortable. Stays cool. Ample coverage. Quality material. They do not creep up. I ordered a medium which I generally take a size small. I have reordered and will reorder again to add more colors to my collection.

Great Value for Cool Thigh Protection
Color: 02-multicolour (4-pack), Size: XX-Large
For the price, I'm not sure there are better women's boxer shortlettes anywhere. I've tried more expensive brands, and for quality and cooling, these are right up there. I have other bamboo viscose undies that still get gross when I get sweaty in the summer, but these, with the large mesh panel, really help wick away a lot of that moisture, keeping you feeling dryer and cooler. I find that the leg openings are comfortable and don't roll up! and the waist band doesn't dig, nor does it roll down. These do not provide any compression, and I wasn't looking for any. I just wanted some cooling, thigh protecting women's boxers that wouldn't break the bank. These are them! Bonus- I've washed them and put them in the dryer (following their instructions), and they haven't shrunk; they look about the same and are nice and soft.
