I'm so happy with this bralette.
I'm so happy with this bralette. The matcha green color is beautiful and the ribbed material is incredibly soft and comfortable. The openback design is a nice touch and looks great under tops. The medium fits me perfectly and provides just the right amount of support for everyday wear. It’s a great combination of style and comfort

Loved the cotton, but poor quality
Size: X-Small, Color: Black, Size: X-Small, Color: Black
I just wore this and was super excited to finally find something in cotton, but it’s falling apart (see picture). I only wore it once (today), and when I took it out of the washer to hang dry, I noticed the back elastic was ripping apart.

3 pack to stay cool
Color: 3-pack（blue,light Red,nude）, Size: X-Large-XX-Large
Unbelievably Soft and My New Wardrobe Staple!
I was on the hunt for some comfortable, basic camisoles to get me through the seasons here in Billings, and I'm so glad I found this 3-pack from BAMBOO COOL. They have completely exceeded all my expectations and have quickly become the most-worn items in my closet.
The moment I took them out of the package, I was amazed by the fabric. It is buttery soft with a cool-to-the-touch feeling that is just incredible against the skin. On our warmer Montana days, this material is a lifesaver—it's so breathable and lightweight that you barely feel like you're wearing it. Unlike some cotton tanks that can feel heavy or trap heat, these keep me comfortable and cool all day long.
The fit is absolutely perfect. They have a wonderful amount of stretch, so they are form-fitting without being tight or restrictive, and they lay smoothly under other shirts without bunching up. The length is great, and the straps stay comfortably in place. I've worn them as a base layer under a cardigan for a chilly evening, on their own on a sunny afternoon, and even just for lounging around the house because they're so comfortable.
Getting three high-quality tops in one pack is such a fantastic value. They've already been through the wash a few times and have held up beautifully, staying just as soft and vibrant as when they were new.
I'm genuinely thrilled with this purchase. If you're looking for the most comfortable, versatile camisoles you'll ever own, look no further. These are a 10/10, five-star must-have!

The Perfect Bamboo Camisoles: Cooling, Warming, and Oh-So Comfortable!
Color: 3-pack（brown,light Brwon,white）, Size: X-Small-Small
I’m absolutely in love with these bamboo moisture-wicking camisoles. They’re everything I could want in a wardrobe staple—versatile, breathable, and incredibly soft. Whether I’m layering them or wearing them solo, they keep me comfortable no matter the season.
Fabric & Feel:
The bamboo fabric is amazing. It’s smooth and feels great against my skin, with none of that clingy or scratchy feeling I’ve had with other bamboo camisoles. The material is both lightweight and substantial, striking a balance between coolness and warmth depending on the weather. It’s like these tanks adapt to my body’s needs!
Moisture-Wicking & Breathability:
The moisture-wicking properties are a game-changer. Whether I’m wearing them under sweaters in the winter or on hot summer days, they keep me dry and fresh all day long. I’ve even worn them during workouts, and they stay breathable and comfortable, even when I’m breaking a sweat.
Fit & Versatility:
The fit is flawless—snug but not tight, although they are more crop designed, and it flatters my body without riding up or bunching. They work perfectly as a layering piece under blouses, sweaters, or blazers, but they also look great on their own for lounging or casual outings.
Temperature Regulation:
One of my favorite features is how these tanks manage to keep me cool in the summer and warm in the winter. The bamboo fabric is naturally temperature-regulating, so I’m always comfortable no matter the season. It’s truly a year-round essential.
Durability & Care:
After several washes, these look and feel as good as new. They don’t shrink, fade, or lose their shape. Plus, they’re easy to care for—I just toss them in the washer on a gentle cycle and they’re ready to go.
Final Thoughts:
These bamboo camis are a must-have for anyone looking for comfort, versatility, and quality. They’re perfect for layering, lounging, or even working out. I’ve already stocked up in multiple colors because they’ve become an essential part of my wardrobe.
10/10—highly recommend for anyone who values comfort and style!
