Customer feedback

It's cool and refreshing, so it's perfect for hot days. I like it because it's stress-free and doesn't feel too tight.

I have sensitive skin, so I get itchy rashes and rashes from the tightness and seams of bras and underwear, but since I started wearing this, I feel really comfortable.
Even when I tried similar products that were cheaper, the difference was clear. I highly recommend it!

I bought these for the first time last summer...and they're so comfortable to wear and have no seams, so I'm free from the itching that I've had from wearing bras under my clothes in the summer, so I bought them again this year.

Customer feedback

The cool feeling is comfortable. It stretches well and fits well. The sweat pads are very thin and don't feel uncomfortable against the armpits, so I'd like to buy them again.

It was so comfortable to wear and I was able to wear it all day. It's so comfortable to wear, so I find myself reaching for it more often.
I wish there were a few more color options.

I bought it again and again. There are no seams on the parts that touch the skin, so it's stress-free to wear, and I can now wear beige, sheer clothes without hesitation, so it's a must-have for me this summer!

Customer feedback

It feels smooth and comfortable against the skin. The fabric is sturdy and can withstand washing. I plan to buy another one.

I chose several similar padded innerwear pieces, and found that the smooth, tightly twisted cotton was the best in terms of texture and how it felt after sweating.

It's comfortable to wear. I bought the pink one and it felt good to wear it under a thin white outfit.

Customer feedback

I bought this last year and it was a lifesaver during the summer. I bought another one this year. It's great because it doesn't make you feel uncomfortable even when you sweat, and it doesn't smell bad. I wear this all the time in the summer.

I sweat a lot and have sensitive skin, so these mesh masks are a great help to me. I love the ice blue one, and it doesn't bother me even if a little bit is visible.

Many of the camisoles I've had lately have been tight fitting, so I was looking for something looser and more comfortable to wear. This is very comfortable. What's more, the fabric is thin and light. The fabric hugs my body, but it's so smooth and light to the touch that I don't even notice it!

TYPE5 Lightweight cotton blend

Recommended for:

  • 夏でも綿にこだわりたい
  • ひんやりした肌触りが好き
  • ほどよいフィット感は欲しい
TYPE5 LINE UP

Customer feedback

It's made of a soft cotton blend and is seamless, so it's very comfortable to wear!

At first I thought it might be a bit thick and hot, but it absorbs a lot of sweat and is great.

It fits the body well but doesn't feel tight and feels good against the skin. The sweat pads are large, so I think it will be useful in the summer.
