Super Micro RaceBase™ is a fine mesh version of the original Super Thermo net. Produced with the same Schoeller® Polycolon® yarn, the fine mesh helps reduce air turbulence against the skin when there is a porous outer layer. The fine mesh allows moisture to transport through the garment keeping you warm and dry. The Super Micro RaceBase™ is perfect under cycling jerseys, Nordic knits and speed suits.

    I will stay with a 4 star rating – it lives up to its billing on dryness and warmth, but the fabric has a rough texture so if the next layer has any roughness (e.g. light fleeced finish) it is hard to pull on and next to impossible to get the sleeves straight. The next layer needs a very smooth inside finish.

    Works great thus far at 30 degrees F with heavy windchill while biking.

    still early so only 4 stars right now – may deserve 5. Used the shirt 4 times for 2hr stretches of XC skiing at 28-34F. Ended up with wet socks, but my torso was dry and comfortable with a thin nylon shirt over the mesh base layer
