Comfortable rugprotector, ook goed voor tourritjes
Comfortabele protector die je na een tijdje niet eens meer voelt. In eerste instantie aangeschaft voor een circuitdag, maar zit zo lekker dat ik heb nu altijd gebruik. Voorheen gebruikte ik alleen een niergordel, maar dan had ik nog wel eens last van mijn rug na lange ritten. Met deze rugprotector heb ik geen last meer van mijn rug na lange ritjes, omdat mijn houding beter blijft. Ik ben tevreden!
