Frequently Asked Questions
Is the SideFill isolated?
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.
How do I wash the SideFill bottle?
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:
Add detergent: Put some dish soap into the SideFill.
Open caps: Open both caps of the bottle.
Fill with warm water: Fill warm water into the bottle from the side.
The water enters the bottle from the side and flows out of the drinking opening. The flow cleans the bottle.
Will the SideFill also be available in other sizes?
Yes, we are already working on another size. It is expected to be available in our online shop by mid-2026.
How long does shipping take?
In Switzerland, the delivery time is 1 to 3 business days.
What are the advantages of the SideFill bottle?
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.
Did you develop the product yourselves?
Yes, the SideFill team managed the entire process themselves – from identifying the problems with conventional water bottles to design and development, and finally implementation.
Die Idee ist super! Ich habe den SideFill fast immer dabei in der Arbeits- oder Freizeittasche. Platzsparend - leicht - praktisch - dicht .... einfach toll!
Guten Tag, ich habe für meimen Sohn eine Flasche bestellt. Wir haben uns sehr gefreut weil die sehr schnell geliefert wurde…. Nur haben wir die falsche Flasche mit dem falschen Namen erhalten.
Auf ein E/Mail an die Firma habe ich seit 3 Wochen keine Antwort erhalten. Das finde ich nicht gut, da mein Sohn die Flasche mit auf die Wanderung nehmen wollte!
Konnte sie erst letzten Samstag das erste mal einsetzen.
Sehr platzsparend und sehr gut zum Nachfüllen. Habe aber das Gefühl, dass das Wasser/Getränk schneller erwärmt als in einer üblichen (dickwanderiger) Flasche. (Hülle benutzt)
Vielleicht, kann da noch was verbessert werden für den stolzen Preis.
Verpackung ist etwas übertrieben, natürlich hochwertig.... ;-) aber nicht mehr zeitgemäss z.B. für die Umwelt.
Freundliche Grüsse
