Professional yet comfortable



At HERENESS, we aim to support mental and physical health through comfortable and functional sportswear. We've spend countless hours studying materials and designs to achieve ultimate comfort without sacrificing performance. As many of us spend more time in casual wear, we decided to start developing comfortable pieces that wouldn't be out of place at the office.

The UNDERCURRENT JACKET can be dressed up for a more formal work setting, or worn casually. It is stretchy even without the use of spandex (polyurethane), which degrades quickly and is not environmentally friendly. This jacket is also wrinkle-resistant, making it easy to care for. The recycled polyester material feels like cotton, making it easy to wear even through long work days.

Highly versatile design

The UNDERCURRENT JACKET has a comfortable fit that works for three seasons, depending on your inner layers. Because it is so versatile, you can save wardrobe space and reduce your environmental footprint from clothing purchases. Although simple in silhouette, it also has functional features including inside and side pockets that can hold your wallet, larger smartphones, and other personal items.

    More than 60% of the fabric is made from recycled polyester, while the remaining is plant-based composite fibers. The material is sufficiently stretchy without blending in spandex (polyurethane), which degrades quickly and is not environmentally friendly.
