Moisture-wicking quick-dry mesh at the inner and outer body helps manage perspiration during active riding, while stretch gussets at the back shoulders and lower waist support natural movement beneath your outer shell. A quick-zip drop-seat function provides convenient access, while YKK zippers throughout add dependable performance. Knit cuffs at the sleeves and lower legs help keep the liner securely positioned, and a soft fleece collar adds comfort around the neck.
