Dryarn® is a high-performance microfibre providing top levels of physical comfort even in the presence of frequent and unexpected changes in climate conditions and variations in the intensity of physical effort. Dryarn’s low coefficient of heat dissipation, prevents any unwanted loss of body heat and at the same time enables the rapid dissipation of excess heat via evaporation of perspiration. This is facilitated through a capillary action where perspiration is collected and carried along the fibre to the surface where it can evaporate. The exceptional stretchiness and comfort of this garment is achieved with XLA® Fibers.

Industry Review

primalblends, based in the home of schizophrenic weather (Colorado), designed the Thermoregulator to be the perfect foundation of any cold-weather wardrobe. It absorbs less moisture, breathes better and transfers more moisture than other fabrics. What's truly amazing is that in cold weather it works like a thermostat, transferring heat and moisture but retaining heat while still transferring moisture when you need warmth. It's comfortable and cozy without being bulky."

Thanks to the garment's anatomical cut, it's outstandingly comfortable. Designed to be worn in sub-zero temperatures, although we didn't manage to test in quite as low as the - 17° C primalblends claims it will work in, we found this to be really effective on chilly night rides."
