Beyond the Bottle: Our Approach to Reusable Design

DRNK makes reusable water bottles for everyday carry. Our approach starts with a simple idea: a reusable bottle only reduces dependence on single-use plastic when it is easy enough to take with you, use often and keep using. That is why our work goes beyond the bottle itself — into product geometry, material choices, packaging and the environmental projects we support.

A reusable bottle only works if you carry it

Most handbags, laptop bags and backpacks are built around flat, rectangular objects. Traditional round bottles can be awkward in that environment, which is why DRNK Slim uses a flat profile just 28mm deep while holding 17oz / 500ml. The aim is practical: make a reusable water bottle easier to carry so reaching for it can become part of the everyday routine rather than another item to work around.

What DRNK does today

• Design for reuse: bottles built around everyday carry and repeated use.
• Durable material choices: 304 stainless steel, Tritan, food-grade silicone and insulated stainless steel constructions selected around how each DRNK bottle is used.
• One bottle, one tree: one tree supported through Ecologi for every DRNK bottle sold.
• Recycled packaging material: reducing reliance on virgin material in our packaging.

We would rather describe what we are doing today than fill this page with vague promises about what we may do in the future. As our products and practices develop, this page will be updated with specific, current information.

Made for repeated use

Reusable design starts with materials suited to repeated everyday use. Across the DRNK range, we choose materials around durability, portability and the way each bottle is intended to be carried.

DRNK Slim Steel

DRNK Slim Steel is made from durable 304 stainless steel in a 17oz / 500ml format. Its 28mm flat profile is designed to slide into laptop bags, handbags and backpacks without the bulk of a conventional round bottle. A leak-proof lid and durable steel construction make it a bottle designed for work, commuting and everyday carry.

DRNK Slim Tritan

DRNK Slim Tritan uses transparent Tritan that is BPA-, BPS- and BPF-free. It keeps the same 17oz / 500ml capacity and 28mm slim format in a lighter bottle, with a fitted fabric sleeve for added protection and easier carrying.

Bubblebottle Silicone: soft, lightweight kids water bottles

Bubblebottle Silicone is a 12oz / 350ml silicone kids water bottle made from food-grade silicone for smaller hands and busy everyday use. At around 195g / 7oz, it is lightweight, soft to grip and flexible enough to handle the tumbles that come with school, play and backpacks without the dents or clatter of a rigid bottle. The soft-touch silicone body is BPA-free, PVC-free and phthalate-free, and the bottle can be hand-washed or cleaned on the top rack of the dishwasher.

The smaller capacity and easy-to-hold shape make Bubblebottle Silicone a practical reusable water bottle for younger kids who need something light enough to carry themselves.

Bubblebottle Steel: insulated kids water bottles

Bubblebottle Steel is an 18oz / 550ml insulated kids water bottle made for school days, sport and older kids on the move. Its double-walled stainless steel construction is vacuum-sealed to keep drinks cold for up to 18 hours, while helping prevent condensation from soaking the inside of a school bag.

The powder-coated steel body is protected by a silicone bumper at the base, and a leak-proof lid with a built-in spout makes drinking easier without removing the lid completely. Like the silicone range, Bubblebottle Steel is made with BPA-free, PVC-free and phthalate-free drinking components and has a removable lid and wide mouth for easier cleaning.

One bottle. One tree.

For every DRNK bottle sold, we support the planting of one tree through our partnership with Ecologi. Tree planting is not a substitute for reducing unnecessary consumption, but it is one practical action we connect directly to every DRNK bottle purchased.

Less unnecessary packaging

DRNK uses recycled material in its packaging and aims to keep packaging focused on protecting the product rather than adding unnecessary layers. We prefer specific actions we can describe clearly over broad claims that a product or package is simply “eco-friendly.”

Designed differently from the beginning

DRNK's approach to reuse is connected to the way the product is designed. The flat form, 28mm profile, drinking position and attached cap design were developed around portability and everyday use. Durability matters, but so does convenience: a reusable bottle that stays at home cannot replace the disposable bottle bought on the way.

Frequently asked questions:

Why did DRNK make a flat reusable water bottle?

DRNK Slim was created to fit more naturally alongside the flat objects people already carry every day. Its 28mm-deep profile is designed to take up less bulky space in a bag while keeping a practical 17oz / 500ml capacity.

What materials are DRNK bottles made from?

The DRNK range includes 304 stainless steel and Tritan for DRNK Slim, food-grade silicone for Bubblebottle Silicone, and insulated double-walled stainless steel for Bubblebottle Steel. Each product page lists the materials used for that bottle so you can choose the format that suits how you plan to use it.

Why choose a silicone kids water bottle?

A silicone kids water bottle can be a useful option for younger children because the material is soft, flexible and comfortable to grip. Bubblebottle Silicone is a lightweight 12oz / 350ml bottle made from food-grade silicone, weighs around 195g / 7oz and is designed to cope with everyday drops and backpack use without denting.

Are Bubblebottle Steel bottles insulated?

Yes. Bubblebottle Steel is a double-walled, vacuum-sealed 18oz / 550ml insulated kids water bottle designed to keep drinks cold for up to 18 hours. The construction also helps prevent condensation inside school bags.

Does DRNK plant a tree for every bottle sold?

Yes. DRNK supports the planting of one tree through Ecologi for every bottle sold. You can read more about the partnership on our Plant a Tree page.

Can I recycle an old DRNK bottle?

Recycling options depend on the bottle material and the recycling services available where you live. Stainless steel is widely recyclable, while plastics such as Tritan may require a suitable local facility. Check the material listed on your product page and your local recycling guidance before disposal.
