The 1.72 Bodywarmer Mk2 used highly technical fabrics: 90g/m2 3-layer eVent windproof breathable fabric on the front, and highly water-repellent stretch woven fabric on the back, the same material used to make the magic swimsuits that smashed world records. The combination of these two materials means warmth and protection on the front and enough breathability on the back to let the sweat out while being nearly waterproof throughout. The higher neck makes you feel more protected and warmer, a full-length lightweight silk-effect YKK zipper, and two pockets on the back, as sometimes you’re forced to wear it for longer than anticipated and it’s good to have access to supplies if needed. Because of the minimal construction, you’ll want to keep heavier stuff in the inside jersey pockets. The 1.72 Bodywarmer Mk2 will become an essential part of your cycling life for years to come. Make the middle back pocket of your jersey its home.
