Stainless steel – including the caps. Hygienic, durable and easy to clean

Made from high-quality stainless steel, the bottle is rust-resistant and particularly easy to care for. Its smooth inner surface prevents residue from building up – for maximum hygiene and effortless cleaning.

Why SideFill was founded

Ordinary bottles were bulky, didn’t fit in a bag and often couldn’t even be filled at small sinks.

That’s why SideFill was developed – a bottle that saves you time and effort and makes everyday life more convenient: slim, hygienic and sustainable.

Our mission: to simplify everyday life with our products while making a positive contribution to the world.

0.1 m² of rainforest per SideFill

With every SideFill sold, we support the protection of 0.1 m² of rainforest in Peru together with Wilderness International.

Frequently asked questions

Is SideFill insulated?

SideFill has been designed to take up as little space as possible in your bag. That is why it has a single-wall construction and is not insulated.

In our own experience, it still keeps drinks cool for several hours, but it does not provide active insulation like a double-walled bottle.

A neoprene sleeve will be available soon. It significantly improves insulation and offers extra protection in everyday use.

How do I wash my SideFill bottle?

SideFill is really easy to clean. 💧

Our experience and feedback from many customers show: no problem at all.

👉 Here’s how:

Open both caps
Add a little washing-up liquid + warm water
The flow rinses the bottle out

✨ As it is made of stainless steel – including the caps – it stays hygienic for the long term.

And the best part: no brushes or complicated tools needed.

Are other sizes planned?

Yes, we are already working on another SideFill size.
