The Benefits of Wearing Cotton Leakproof Underwear

We’re launching an all-new cotton super leakproof lace bikini– but that’s not the only reason you should consider rocking cotton undies.

Cotton is one of the most common clothing materials in the world. From your favorite t-shirt to your comfiest pair of pyjama pants, chances are you probably already have a closet full of cotton to choose from. But is there enough cotton in your underwear drawer? With the launch of Kt’s new Cotton Super Leakproof Lace Bikini, there’s never been a better time to throw some cotton underwear into your daily mix. From its breathable nature to its downy softness being a more sustainable alternative to synthetic fabrics, there are numerous reasons to add cotton undies to your daily rotation. Read on to learn more about the benefits of wearing cotton underwear.

It’s breathable
If you have a vagina, you know that it can be super delicate and sensitive to irritation or infection. This means you have to treat it gently when it comes to the fabrics that are going to be getting close to it every day. According to a study conducted by the University of California, Berkeley, yeast infections are more likely to be caused by wearing underwear made from synthetic materials. Synthetics can trap heat— keeping your bits a bit too nice and toasty — which only promotes more yeast growth.

It’s 100% natural
Being a natural material, cotton has a lot of benefits, especially when it’s going to be up close and personal with a sensitive zone like a vagina. “The vulva is a very sensitive and delicate area, similar to the lips on your face. You want to treat [it] gently,” explains Dr. Alyse Kelly-Jones, board-certified OB-GYN — and the best way to treat it gently is by wearing a natural material, such as cotton. Cotton will help keep potential yeast infections at bay, prevent unpleasant itching, and its super absorbent nature helps keep you dry, even during the most sweaty of activities. Our newly updated Cotton Super Leakproof Lace Bikini is soft and super breathable– great for wearing in any kind of weather. For those looking for different-looking versions of our cotton undies, these are sure to be the right fit– featuring an all-new softer waistband for ultimate comfort.

It’s comfortable

There’s a reason why so many baby clothes are made of cotton – it’s soft, soothing, and offers plenty of ease of movement. Cotton simply feels good on the skin. This makes it the ultimate fabric to wear when you’re on your period and could use a bit of extra soothing comfort. It’s also the most comfortable underwear option if you have sensitive skin in general, or are allergic to synthetic materials like nylon or polyester. 

It’s also pretty convenient — okay, maybe we planned it — that our new Cotton Super Leakproof Lace Bikini is made with our Super Leakproof technology in the gusset. This means that they are naturally ultra-absorbent— they can hold up to 8 tsp (that's equivalent to 8 pads or tampons) of liquid! Depending on your flow, you may be able to completely eliminate pads, tampons and or a menstrual cup from your period routine while wearing our cotton period panties. We can’t think of a more comfortable pair to wear (it rhymes!) during your cycle.

It’s absorbent
Cotton underwear is naturally absorbent– meaning that we believe they're the best underwear to wear whether you're working out or relaxing at home. It doesn’t hold onto sweat and acts as a temperature regulator, keeping you nice and dry no matter what you’ve got going on.

Ultimately, cotton is soft, 100% natural, super absorbent and naturally breathable– that’s why we chose to make our Cotton Super Leakproof Lace Bikini with it. Moreover, the lace trim adds a dainty touch, so you can be confident that you’re wearing cute underwear – whether you’re on your period or not. Need we say more?
