Sunnies Inc. was established in 2013 as a sunglasses retailer before expanding into prescription eyewear through Sunnies Studios. As the company evolved into a broader lifestyle business, it introduced new categories including cosmetics (Sunnies Face), coffee (Sunnies Coffee), and hydration products (Sunnies Flask). According to the company, the goal of Sunnies Flask is to make hydration more enjoyable through products that blend utility, aesthetics, and personalization. [1]

The brand launched with an emphasis on modular design, enabling customers to customize nearly every visible component of their flask.

Sunnies Flask is built around three primary ideas:

• Customization — allowing customers to personalize the appearance of their flask.

• Functionality — creating insulated bottles designed for everyday use.

• Lifestyle Design — treating reusable bottles as fashion accessories as well as practical products.

The company markets the product as “the most customizable flask ever,” offering hundreds of thousands—and later over one million—possible color combinations depending on the available components. [1]

Bottle Types

The lineup includes several bottle styles:

• Stainless Steel Flask

• Lite Bottle (made from Tritan plastic)

Available capacities include:

The products are aimed primarily at consumers seeking reusable drinkware that doubles as a personal style accessory.

Since its launch, Sunnies Flask has attracted attention for its extensive customization options and modern aesthetic. Online discussions have generally praised the modular design and color selection, while some users have raised concerns about pricing, durability of certain finishes, ease of cleaning some cap designs, and comparisons with other insulated bottle brands. These viewpoints reflect user opinions rather than verified product testing. [2]
