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.

Suggested Active-Use Starting Window

40°F to 70°F

4°C to 21°C

A practical starting window for sustained, high-output use. Super Micro is designed to cool efficiently in warmer conditions and to work beneath close-fitting or porous outer layers. In colder weather, the full system above it determines how much warmth is retained.

Cool Conditions Warm / High Output
20°F -7°C
40°F 4°C
70°F 21°C
80°F 27°C

Temperature windows are approximate, not safety ratings. Super Micro is selected primarily by activity level and outer-layer permeability. Comfort varies with metabolism, pace, sun, wind, humidity, and the complete clothing system.

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
