Warmth Made of thin (19.5 micron) merino fibers with 50 percent acrylic, the Nova is super soft with zero itch. “I got thoroughly soaked in a surprise downpour in the Wallowa Mountains,” an Oregon tester says. “The hat was dripping, but my head stayed warm, even when the sun set and temps dipped into the mid-20s.” Gripe: Despite the acrylic content, the Nova took 24 hours to completely dry.
Versatility It’s light and thin enough to wear under most helmets. “It wicks and breathes well up into the high 50s,” reports a tester.
