The Best Reusable Water Bottle: The Dopper Original vs The FLASKE Bottle

FLASKE Reusable Water Bottle

If you’ve decided to ditch bottled water and become more sustainable, then you’re probably wondering which is the best reusable water bottle to buy. There are plenty out there. In theory, they all do the same job. In practice, some are definitely more efficient than others. 

Today, I’m going to compare two of the most popular reusable water bottles on the market. The Dopper Original and the FLASKE Bottle. Both come from innovative and environmentally conscious Dutch companies, but these refillable water bottle have several different features. 

Ask yourself the following questions before choosing your own eco friendly water bottles.

What size reusable water bottle do you need?

The Dopper Original holds 450ml of liquid, that’s a convenient size to pop in your day bag and plenty if you know where to refill your reusable bottle. But sometimes you’ll need a larger or smaller bottle. The FLASKE bottle comes in four sizes so you can have a bottle for full days on the go, zero waste travel, exercise, or commuting.

FLASKE Bottle sizes

What’s your favourite colour?

Do you want your double walled water bottle to reflect your personality and match your outfit? Purchase a Dopper Original bottle, and you’ll have a choice of five matte colours. Purchase a FLASKE Bottle, and you can choose from several colours with a matte or metallic finish. Do floral patterns and tropical prints take your fancy or do you prefer a sleek black or while bottle? Or, how about a camouflage bottle that kids will love? The FLASKE Bottle comes in all these designs and more!

Is stainless steel better than plastic?

Reusable plastic water bottles are cheaper and lighter than metal bottles, but stainless steel water bottles are more robust, more healthy, and better for the environment. 

The Dopper Original is made from recyclable BPA-free plastic and it’s much tougher than single-use plastic bottles. However, it’s still made from plastic. Stainless steel is a safer material than plastic because it’s non-toxic and non-porous. With an 18/8 food-grade stainless steel bottle you don’t get bad odours, mould, or rust.

Do you want an insulated reusable water bottle?

The FLASKE Bottle is double walled and insulates both hot and cold beverages. It keeps your drinks hot for up to 12 hours or chilled for up to 24 hours without any condensation on the outside. An double insulated water bottle is perfect for the daily commute and wintertime, as well as summer picnics, outdoor excursions, and camping trips.

What extra features do you want?

The Dopper Original has a smart design where the bottle top doubles as a small cup. Instead, FLASKE offers an interchangeable sports lid so you can stay hydrated during your workouts. You can also customise your FLASKE Bottle with a carabiner and hang it from your bag or engrave it with your own name (engraving coming soon).


What will the reusable water bottle cost?

If you usually buy bottled water, then buying a reusable water bottle will save money in the long term. In the short term, a Dopper Original will cost you €12.50. An insulated FLASKE Bottle costs €29.95, it’s more expensive, but it can last a lifetime.


Do you want to protect the environment?

Both FLASKE and Dopper donate a portion of profits to environmental nonprofits or charitable projects. When you buy a reusable water bottle from FLASKE, not only do you minimise your plastic waste and set an eco-friendly example, but you also support the Plastic Soup Foundation
