In short: premium silicone performs best against salt water and intense sweating. Bioceramic is water-resistant and sweat-proof under light perspiration, but is more geared toward daily use than intense sports.
Silicone: built for active use
The high-quality silicone used by Royal Pop Style is sweat-proof, salt-water resistant, and UV-stable — designed for swimming, training, and outdoor sports.
Bioceramic: resistant but not sporty
Bioceramic is water-resistant and sweat-proof, ideal for daily use and light activities, without being optimized for prolonged or intense immersion.
Our recommendation by use
- Swimming, intense sport → Silicone/Bioceramic
