Designed for mountain biking and motocross, offering protection through a soft, impact-hardening foam called IPX® and a durable Kevlar® outer layer. They feature adjustable straps for a secure fit, and breathable, quick-drying materials for comfort.
- IPX® impact protection: The core of the Sinner's protection is the IPX® foam, which is soft and flexible during normal riding but hardens instantly upon impact to absorb shock. An earlier model used SaS-Tec memory foam with similar properties.
- Kevlar® abrasion resistance: Many Sinner models incorporate a durable Kevlar® layer on the outer shell for added protection against scrapes and tears.
- Comfortable and secure fit: The pads have multiple Velcro® straps, along with perforated neoprene and a soft inner lining, to provide a secure, slip-free fit. Some models also use a silicon print on the inside to further prevent slippage.
Breathable design: The use of breathable, quick-drying materials and perforated neoprene helps with ventilation, although some reviewers note they can still be warm on hot days.
