Handmade Straps
Bio Rubber Strap for Apple Watch – Yellow | Milano Straps Lab
€45,00
Biodegradable rubber has a different texture from traditional rubber. Softer under the fingers, less synthetic to the touch – it can be worn all day without your wrist noticing it.
This Apple Watch strap is made in the Italian laboratories of the Milano Straps Lab collection, from 100% biodegradable material. The yellow is bold, not understated: it is neither a pastel yellow nor a fluorescent sports yellow, but a color that makes a statement on the dial and holds it.
Bio-rubber is not a concession to ecology at the expense of function. It withstands daily use, moisture, and movement. It ages slowly and consistently. Each piece has slight surface variations inherent to the material – not defects, but character.
For those who choose not to wear animal leather without sacrificing a well-made accessory.

But how does this bio rubber really behave with sweat and humidity? Can I wear it at the gym or on a beach vacation without issues?
Yes, it handles daily use, moisture, and movement. It is not a material that degrades on contact with water or sweat. The difference from traditional rubber lies in the feel — softer and less synthetic — not in functional resistance. The important characteristic is that it ages slowly and consistently, so it maintains its performance over time.
What is the exact difference between this and a standard rubber strap? Why should I pay for ‘biodegradable’ if I am going to wear it for years anyway?
Biodegradable rubber has a completely different consistency: it is softer to the touch, with none of the synthetic or plasticky feel of traditional rubber. You can wear it all day without your wrist noticing it. The biodegradable aspect is an intrinsic characteristic of the material itself, not a functional sacrifice — it simply means that when its lifecycle ends, it will not remain in circulation for a hundred years.
Is this yellow like sports gear or more understated? Does it risk becoming tiresome?
No, it is not a fluorescent sports yellow or a pastel shade. It is a decisive yellow that makes a statement — placed against the dial, it commands attention. It is a conscious chromatic choice, not a compromise. If you love yellow, this will not disappoint you; if you do not embrace it, this is probably not for you.
Are all pieces identical or does each strap have slight variations?
Each piece displays subtle surface variations inherent to the material. These are not defects — they are the intrinsic character of bio rubber. It means your strap will have its own unique materiality, much as natural materials do.
Will it work with all Apple Watches or do I need to check my model?
It works with all Apple Watch models that have the standard lug attachment. If your watch accepts standard Apple interchangeable straps, this strap is compatible.
