Fine-mesh cooling and moisture transport for fast, high-output movement.

Super Micro is Brynje’s fine-mesh polypropylene baselayer for high-output activity and warmer conditions. The smaller cells move moisture away from the skin while reducing air turbulence beneath porous or close-fitting outer layers, making it especially effective under cycling jerseys, running layers, Nordic kits, and speed suits.

Why Fine Mesh Works

Super Micro uses smaller mesh cells than Super Thermo to maintain moisture transport while creating a smoother layer beneath performance clothing. The fine structure reduces turbulence in the air held against the skin, vents heat efficiently during hard efforts, and dries quickly when output drops.

That Means:

Fine cells move moisture with minimal fabric against skin

Enhanced cooling during sustained high-output activity

Smoother performance beneath jerseys, race suits, and Nordic kits

Very low moisture uptake and rapid drying
