Merino Trail Hoodie

Merino wool has been regulating temperature for sheep in harsh alpine environments for centuries; the Merino Trail Hoodie borrows that biology and puts it to work during hikes, travel days, and everything in between. At 18.5 microns — finer than a human hair — this grade of Merino wool doesn’t itch. It drapes softly against skin and handles in a way that feels more like a premium cotton fleece than anything you’d associate with traditional wool.

The thermal regulation story is what makes Merino genuinely different from synthetic fleeces. Merino fibers are hygroscopic — they absorb up to 35% of their weight in moisture without feeling damp — and release it as the temperature shifts, creating a passive cooling and warming system. In practice this means wearing the same hoodie comfortably from a crisp 35°F dawn summit to a 70°F afternoon trail without ever feeling too hot or too cold.

The odor resistance is equally functional. Merino’s natural crimp structure and lanolin coating inhibit bacterial growth, the primary cause of athletic odor. On multi-day hiking trips or travel days when laundry isn’t an option, you can wear this hoodie for two or three days before it needs washing. When it does need a wash, it goes straight in the machine on a cold gentle cycle — no handwashing, no specialist detergent required.
