In terms of protection, even without the airbag installed, the Big Sur gear receives top marks. For added durability in high-impact zones, it features Armacor fabric, a weave of Cordura and Kevlar that's both highly abrasion resistant and still breathable. In the shoulders, there's a molded TPU protector beneath the jacket's outer layer that provides impact protection and maintains the jacket's shape (useful, I suppose, for when you want a pseudo-plus-one at your favorite diner). Generously sized CE-certified shoulder, elbow, and knee protectors are included. Thin foam chest protectors and hip protectors are also included, but feel more like stand-ins for the real-deal stuff found everywhere else. Sans airbag, the jacket can accommodate a back protector.
