Handmade Straps
Bio Rubber Strap for Apple Watch — Daily Use and Sport
€45,00
Bio rubber is not traditional rubber. It's a material born from a precise choice: to reduce environmental impact without sacrificing performance. It feels soft on the wrist, conforms to the shape of the arm, and doesn't irritate even after hours of continuous contact.
For those who wear their Apple Watch all day — from the desk to the gym, without changing straps — this is the right compromise. It doesn't yield to sweat, doesn't stiffen in the cold, and maintains its shape over time. Flexibility is not weakness: it is the strength of this material.
Available in multiple colors, it adapts to different contexts without forcing anything. It's not a strap that wants to be noticed — it's one that works.

Ogni cinturino è un pezzo unico, tagliato e cucito a mano nel nostro atelier di Milano. La tecnica della cucitura a sella garantisce una resistenza superiore, mentre i bordi sono rifiniti con sette strati di tintura applicata a pennello, assicurando una longevità che sfida le tendenze passeggere.

I have a doubt: does bio rubber truly withstand gym sweat, or does it stay slimy on the skin?
It does not give way under sweat — this is one of the reasons this material was chosen. The slimy issue does not arise as it does with certain traditional rubbers. It remains soft to the touch, adapting to the skin without that sticky sensation. You can wear it directly after a gym session without needing to dry it.
Is it truly the strap I can keep on from the office to a run, or is it still a good idea to switch?
It was created precisely for this: for those who want a single strap from the desk to training, without changing. It does not irritate even after hours of continuous contact. If you wish to keep it on all day, there is no reason to remove it. It is a different matter if you prefer to vary out of habit — that depends on you.
How does it behave in the cold? I’m afraid it might stiffen like certain old rubber straps.
It does not stiffen in the cold. This is one of the specific characteristics of bio rubber: it maintains its flexibility even when temperatures drop. You will not find that unpleasant rigidity that the old traditional rubbers had.
If I buy two different colours, will they match exactly, or will I end up with two slightly different shades?
Slight chromatic variations between one piece and another are possible, due to the very nature of the material. Two straps of the same colour may have slightly different nuances. This is not a defect — it is how bio rubber works.
I would like to know how well it keeps its shape over time: after a few months of daily use, does it return to like new, or does it start to give way?
It maintains its shape over time. The flexibility of the material is its strength, not a weakness — meaning it does not lose memory and continues to sit well on the wrist. It is not a strap that deforms with use.
