When compared to rubber - silicone feels a lot more comfortable on the skin, and is non-toxic and eco-friendly.
Silicone also has a good high and low-temperature resistance and will not deform.
These two-piece silicone straps are great for smart watches such as they don't cover the heart-rate sensor.
Note: our silicone two-piece straps are not compatible with some Garmin watches.

When you need a watch strap that laughs at water, sweat, and everything in between, silicone watch straps are the answer. These two-piece straps are built for active wear — completely waterproof, incredibly comfortable, and tough enough to handle the gym, the pool, the beach, and everything in between.
Unlike NATO straps which thread under the watch, our rubber and silicone straps use a traditional two-piece design that keeps the caseback flush against your wrist. That's a big deal if you're wearing a smartwatch or fitness tracker — your heart rate sensor stays in contact with your skin, so no gaps in your data.
What makes silicone better than standard rubber? It's softer, more flexible, hypoallergenic, and handles temperature extremes without going brittle or sticky. It's also completely odour-resistant — no funky smells after a sweaty workout. Most premium "rubber" straps on the market are actually silicone, and ours are no exception.
Every strap material has its strengths. Here's where silicone really shines:
Choosing between strap materials depends on what you're doing and what matters most to you:
| Feature | Silicone/Rubber | NATO Nylon | Leather |
|---|---|---|---|
| Water | Fully waterproof ✅ | Water-resistant, quick-dry | Avoid water ❌ |
| HR Sensor | Compatible ✅ | Blocks sensor ❌ | Compatible ✅ |
| Comfort | Soft, flexible | Lightweight, breathable | Moulds to wrist over time |
| Best For | Sport, diving, daily beater | Casual, military, everyday | Dress, smart-casual |
| Durability | Excellent — doesn't degrade | Good — edges may fray | 1-3 years with care |
The short version: if your watch is going anywhere near water regularly, or you're wearing a smartwatch with a heart rate sensor, silicone is the way to go. For everyday casual wear, NATO straps are hard to beat. And for dress occasions, leather is still king.
Silicone straps work with any watch that has standard spring bar lugs, but they're especially good on:

Silicone is a synthetic rubber that's softer, more flexible, and more skin-friendly than natural rubber. It's hypoallergenic, handles extreme temperatures better, and doesn't develop that sticky feeling cheaper rubber straps get over time. When we say "rubber strap," we mean high-quality silicone.
Absolutely. Silicone is 100% waterproof — salt water, chlorine, fresh water, doesn't matter. It won't absorb moisture, won't develop odour, and dries in seconds. It's the best strap material for any water activity.
Yes, and that's one of their biggest advantages. Our silicone straps are two-piece design, so the caseback stays flush against your skin. Unlike NATO straps which add a layer between the sensor and your wrist, silicone keeps everything in contact. Ideal for Garmin, Samsung, and other fitness watches.
Measure the lug width on your watch — the gap between the lugs where the strap attaches. Most watches use 20mm or 22mm. Our silicone straps come with quick-release spring bars, so swapping takes seconds with no tools needed.
Dead easy. Warm water, a drop of mild soap, quick rinse, done. Silicone doesn't absorb anything, so there's nothing to deep-clean. Wipe dry or let it air out — takes a couple of minutes at most.
