Particularly Hygienic
Easy to clean and made of durable stainless steel
The SideFill was designed to take up as little space as possible in your bag. That's why it's a single-wall construction and not insulated.
Based on our own experience, it still keeps its contents cool for several hours, but it doesn't offer active insulation like a double-walled bottle.
A neoprene sleeve will be available soon. This significantly improves insulation and offers additional protection for everyday use.
The SideFill bottle is made of 100% stainless steel, making it particularly easy to clean, unlike conventional water bottles which are often at least partially made of plastic.
Here's how:
The water enters the bottle from the side and flows out of the drinking opening. The flow cleans the bottle.
Yes, we are already working on another size. It is expected to be available in our online shop by mid-2026.
In Switzerland, the delivery time is 1 to 3 business days.
You primarily have two advantages that regular water bottles don't offer you.
1. Convenient Refilling: You can refill the bottle even at small sinks. This saves you time and gives you more flexibility in your daily life.
2. Space-Saving Design: The bottle's flat design frees up space in your bag. This gives your bag a pleasant, organized feel, and you have more room for other things.
Yes, the SideFill team managed the entire process themselves – from identifying the problems with conventional water bottles to design and development, and finally implementation.
The SideFill bottle is "patent pending."
