Merino wool fibers are ultra‑fine, allowing for exceptional softness without itch. They’re naturally thermoregulating, moisture‑wicking, and odor‑resistant—so you stay comfortable and fresh whether you’re in the boardroom or on a backcountry trail.

We use ultra‑fine Merino fibers—thinner than traditional wool—for next‑to‑skin softness and itch‑free comfort. While we don’t publicize the exact micron number, our knit structure and fiber selection ensure a balance of softness, durability, and resilience.

When cared for as directed, your Merino garments will hold their shape and size through hundreds of cycles. Always follow our simple care instructions to keep them looking like new.
