Description

Soft-shell rain, transitional seasons, and indoor spaces that shift in temperature throughout the day. The wardrobe gap most active men encounter is not deep winter or peak summer, but everything in between. A lightweight merino hooded pullover is designed to fill that gap. Merino wool has been used across a wide range of environments for its natural structure: crimped fibers help retain warmth while allowing airflow, supporting comfort across changing conditions.

The versatility of this merino wool hoodie comes from how it layers. In mild conditions, it can be worn on its own with the zip adjusted for airflow. In cooler weather, it pairs easily with an outer layer, with the 190gsm fabric sitting close to the body for effective layering. In colder conditions, it works as part of a layered system under an insulated jacket. This is what lightweight merino is designed for - not a single-use layer, but one that adapts across different environments.

Designed for a wide range of activities, from day hikes and travel to everyday wear and commuting. The same top transitions easily from outdoor use to casual settings, sitting clean under a jacket and working well in indoor environments with fluctuating temperatures. Merino wool helps reduce odor buildup, allowing for multiple wears between washes compared to typical fabrics.

The value of merino comes from repeat use across seasons. This piece is built for consistent wear through changing conditions, reducing the need for multiple layers in your rotation. It also requires less frequent washing than many standard fabrics, helping simplify care during travel or busy weeks. Gift-ready out of the bag.

Color

Green Olive, Black, Charcoal Marle, Grey Marl, Indigo Blue, Bayberry Green, Cabernet

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

Your default layer, three seasons a year

Your default layer, three seasons a year

Cool morning? Zip up. Sun's out? Vent the collar and push the sleeves. This half-zip covers the range where most people carry two jackets — without the swish of synthetics.

Details that earn their place

Details that earn their place

A stand-up collar blocks wind on the neck, the zipper garage keeps metal off your chin, and ribbed cuffs hold their shape wash after wash. Simple, deliberate, durable.

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.

Warm enough without a jacket?

Down to cool-autumn temperatures, yes — especially when you keep moving. In deep winter it becomes a serious mid-layer under a shell.

Will it pill?

Light pilling in high-friction spots during the first weeks is normal for natural fibers and fades with wear. A fabric shaver removes it in seconds.

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.
