Example Sentences

“We have a signature snap on the back of the collar and functional details like bi-swing back panels, that extend out for extra range of motion, and vented underarm footballs, because these are real riding jackets. The leather is heavy and rugged, so we use heavy-duty asymmetric zippers, designed not to ripple when you lean over a motorcycle.”
