Belly Bandit has launched a nifty device to help all those women who feel uncomfortable in their tight-fitting underwear.

 And the product is already getting endorsed by scores of 5-star reviewers.

Costing a measly £22 ($27.25), Don’t Sweat It bra liner prevents perspiration in hot summers by sitting under your underwear.

The product comes with a lightweight bamboo layer to absorb all perspiration while adjusting itself to match a person’s body shape.

Describing the bra liner, the post-pregnancy shapewear brand writes on its website: “It’s time to cut the B.S. – Boob Sweat, that is!

“Our Don’t Sweat It bra liners minimize the effects of unsightly and uncomfortable under-boob perspiration. Simply slide our discreet liner beneath the bottom of your bra and say goodbye to wet clothes and irritated skin.

“Our soft, viscose from bamboo material gently absorbs moisture while moving with your body.”

“Any size, any age or any activity—these sweat soakers are the perfect way to stay dry and comfortable around the clock,” the description adds.

Since it was released, the product is being hailed useful by dozens of customers, who said it is a ‘must have’ thing.

One user wrote: “Don’t Sweat It was wonderful, whether at the gym working out or just every day, it is soft, comfortable and moisture absorbent.

“I wash it out every night and have since bought an additional two.”

Another wrote: “The ‘Don’t Sweat It’ have been a life saver this summer during my pregnancy!! They help absorb excess sweat and also provide padding between the underwire of my bra and my growing belly.

“They are very comfortable! I definitely notice a difference when I don’t wear them!”

Yet another person said: “Can’t wait to use the Don’t Sweat It this summer. I have used it a few times just to see if it is comfortable and it is!

“It never slips around and I don’t even notice it.”
