Insulated monosuit liner with 120g Thermal Flex™ warmth, moisture-wicking mesh, stretch mobility, and drop-seat access.

Add warmth to your favorite uninsulated monosuit with the FXR Insulated Monosuit Liner. Designed as an easy cold-weather layering piece, it features 120g Thermal Flex™ insulation for a maximum warmth rating of 4, helping extend comfort when temperatures drop without replacing your outer shell.

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. A quick-zip drop-seat function adds convenient access, and YKK® zippers throughout provide dependable performance. Knit cuffs at the sleeves and lower legs help keep the liner securely positioned, while a soft fleece collar adds comfort around the neck.
