Soft, slinky cooling tee without that synthetic feel
Color: Grey, Size: Medium, Color: Grey, Size: Medium
I ordered this bamboo viscose CoolMax t-shirt in gray, size medium because I wanted something lightweight and breathable for workouts and just being around the house when it is hot. The standout feature to me is the super soft and slinky feel it has without the overly cool wet feeling you get from other shirts made from synthetic “cooling fabric.” It feels smooth and comfortable against the skin while still doing a great job keeping me dry and not clingy. The fabric is lightweight with a nice stretch, and it moves easily without losing its shape.
The fit is very flattering with a clean shoulder line and a curved hem that sits right at the hips, so it looks polished enough to wear out, not just for the gym. The seams are flat and smooth, and the tagless design makes it easy to wear all day without irritation. It also holds up well after washing with no shrinking or shape issues. For sizing reference, I am 5'6", 119 pounds, 34B, with a 28.5" waist, and the medium fits me exactly like the model in the main listing picture, exactly. That should really help with sizing decisions if your build is similar. Highly Recommended!

Lightweight and comfortable to wear.
Color: White, Size: Medium, Color: White, Size: Medium
I wanted something comfy, lightweight, breathable, durable, and cool to wear while working out. My old t-shirts leave a lot to be desired. This Bamboo Viscose Coolmax T-shirt meets all the above. The only downside for me is that I chose white, and the material is very thin and see-through. If you prefer to dress more modestly as I do, you’ll want to select a darker color. I planned to only wear it in the house or while sitting outside on the patio, so it’s okay. Comfort and breathability are important to me when the summer heat and humidity hit.
The length and cut fit my physique and are comfortable to wear and move in. I got a medium, and it fits perfectly, which was really a nice surprise. Many tops tend to be too long or too tight in the hips. I’m 5’4” and 130 lbs.
The top washes up nicely, but ended up with a few wrinkles. No big deal for me, though.
Is it worth the price? I’d say it is based on the quality, fit, comfort, and breathability of the fabric. I’ve passed up buying similar tops when shopping because they were more expensive than this one. It’s a top to wear when working out, not for a night out on the town. It shouldn’t cost a fortune. At the time of this review, it’s on sale for $5.00 less, making it an even better bargain.

Better than any other!
Color: Set8-3, Size: Small
I've purchased this item twice now, they fit so we'll and are made great. The best part is the don't ride up or move around while I work. I'm very busy and move a lot, bending, squatting, twisting and these panties move with me. They don't shrink or fade. I highly suggest this item if your looking for a good set of panties that stay put without breaking the bank. Very comfortable and breathable. ****An update to my last review**** After washing the second pack that I got, they started coming apart. The legs seams were unhemmed and frayed in the washer.

Stretchy and comfortable!
These underwear are exactly what I was hoping for! Love the look of having a seam without actually having one. They are soft, comfortable, and stretchy! Which is great for me because I have endometriosis so often have bloat days. Highly recommend! True to size.

Great fit! Very comfortable
I was skeptical but these ended up being such a great purchase that I came back for more.
I'm between XS and S so I ordered the Small and they fit perfectly. As a runner I have quite large Quads and have a hard time finding boy shorts that don't roll up or cut off circulation. These shorts I have neither of those issues and they're so comfortable. Soft, stretchy material that also doesn't dip at the back. Perfect!
