Karl Wong, the founder and designer of Karner, is passionate about fitness and design. He sought to combine these two worlds by creating a lifestyle and fitness accessories brand. Wong identified an opportunity to produce a functional fitness bag that is comfortable to carry and has practical compartments for organizing the user's belongings. He believes that functional training is essential in preparing individuals for everyday challenges. Wong observed that existing fitness bags were too technical or simple, lacking compartments or durability. While some bags were stylish, they were not practical for gym use. Other bags had too many pockets, making locating items challenging.
