The T-SPS Air Jacket is a versatile, warm weather riding jacket from Alpinestars that includes a thermal liner. The advanced poly-fabric main shell offers high levels of tear and abrasion resistance. Large panels of mesh keep you supplied with a steady stream of fresh air. Additional zippered vents are located vertically at the torso and the thermal liner can be added to cut airflow and insulate the rider when temperatures drop. Continuing the light, comfortable vibe of the T-SPS Air Jacket is Alpinestars' Nucleon Flex Plus shoulder and elbow armor.
