Once you've tested the comfort of a sweat-wicking t-shirt, there's no going back to a classic cotton t-shirt.

But how can a t-shirt keep you so dry and cool when you know you're sweating profusely? The secret is a fabric that wicks away moisture.

With classic underwear, sweat settles on the fibers of the garment. If it is made from a natural fabric such as cotton, moisture is absorbed by the fibers. The T-shirt is then damp and heavy.

HYP underwear, uses a process called "capillary action". The fibers keep the sweat on the surface and, like channels, transport the sweat to the outer layer of your t-shirt. From there, the sweat evaporates into the air. You are then perfectly dry.

You might be wondering why this underwear is so effective, the answer lies in our advanced technology. The innovative technology used to make this sweat resistant underwear not only keeps sweat out of your clothes less, but also helps regulate your body temperature.

This is a great advantage as you will stay cool and dry all day. You can wear it with shirts, t-shirts, sweaters...
