Purposeful and practical design is part of Whistles DNA, and our Koa is nothing short of these principles. Sized to fit just the essentials, it’s crafted from soft leather and has a snap-stud flap pocket to store your cards and a secure zipped coin purse. The metallic gold finish, embossed with the Whistles branding, adds a playful touch and is easier to spot when carrying it in your bag.
