Merino is easier to care for than most people expect — and because it naturally resists odor, you'll wash it far less than cotton or synthetics.

Washing

  • Machine wash cold (30°C / 86°F) on a gentle or wool cycle
  • Use a mild detergent — no bleach, no fabric softener (softener coats the fiber and reduces its natural performance)
  • Wash with similar colors, inside out

Drying

  • Lay flat to dry away from direct sunlight — this keeps the shape and fit
  • Do not tumble dry, do not wring

Between wears

  • Air it out overnight — merino refreshes itself and is usually ready to wear again
  • Spot-clean small marks with cold water instead of a full wash

Storage & pilling

  • Store folded, clean and fully dry
  • Light pilling in high-friction areas during the first weeks is normal for natural fibers — remove it gently with a fabric shaver and it fades over time

MERINNOVATION Mens Merino Wool T-Shirt - Men Merino Wool Shirt Lightweight Wicking Base Layer Undershirt for Hiking Travel

THE MERINNOVATION STANDARD

One shirt for every forecast

Superfine merino that works as hard on a trail as it does at a desk.

Thermoregulating
Traps warmth when it's cold, releases heat when you move — comfortable from winter layering to summer wear.
Odor-free for days
Naturally antibacterial fiber. Wear it for days — even on the road — and it stays fresh.
Zero itch
Superfine fibers bend against the skin instead of poking it. Softer than you think wool can be.
Built to last
Flatlock seams, a reinforced collar, and a 1-year warranty on every piece.
From trailhead to boarding gate

From trailhead to boarding gate

One shirt that hikes all day, dries overnight in a hotel sink, and still looks sharp at dinner. Merino wicks sweat before it sits on your skin and shrugs off odor even after back-to-back wears.

Cut for real life

Cut for real life

A clean regular fit that layers under a jacket without bunching and stands alone without clinging. Flatlock seams sit flush against the skin — nothing rubs on mile ten or hour ten.

Good to know
Will it itch?

No. We use superfine merino fibers that bend on contact with skin instead of prickling it. If you've only worn traditional wool, the difference is immediate.

Can I wear it in summer?

Yes — merino is a temperature regulator, not just insulation. It wicks moisture and releases heat, which is why desert hikers and marathon runners wear wool in the heat.

What if I'm between sizes?

Size up for a relaxed everyday fit, or stay with the smaller size for a snug base layer that sits close under other clothing.

How do I wash it?

Machine wash cold on a gentle cycle, lay flat to dry. No softener, no tumble dryer. Between washes, just air it overnight — merino refreshes itself. Full details in our care guide.

Wash less. Wear more. Merino resists odor naturally — air it out overnight and it's ready to go again. When it's time: cold wash, lay flat.
