World's Finest Wool

Merino is not a grade of wool, it's a specific breed of sheep that produces nature's most advanced performance fiber. Where traditional wool measures upward of 25–40 microns in diameter, Merino fibers fall between 11.5 and 22 microns. For scale, a single human hair measures around 40 microns. That microscopic difference is what makes merino wool so soft and wearable in additional to all it's great properties: it breathes when you're working, insulates when you stop, and stays warm even when wet. First Lite builds on nothing less.
