These bike pants offer the tapered fit, articulated knees, and other features for pedaling, pumping, and setting the fastest split times on the track. We selected a lightweight cotton blend that is thin yet strong, like a carbon nanofiber filament. It's also a soft, stretchy fabric for unencumbered mobility, drastically reducing fatigue. Ripton's design team was persnickety about how these pants should fit. The result is a sculpted, multi-panel knee shape that accommodates pads and feels weightless when you're in a riding position. Further, a high back rise and tapered cuffs make this our most purpose-built bike pant ever. For keys, burner phones, and Gold Bears, there are two zippered pockets on either quad, well away from your hips. An integrated webbing belt lets you fine-tune the waist fit. Elasticized cuffs have reinforced fabric on the scuffing sides of your ankles
