Natural Performance
An innovative blend of 75% TENCEL™ Lyocell and 25% Merino Wool. Lightweight and breathable, built for outdoor training in cool conditions.
Microplastic Free
Both fibers are fully natural, so nothing plastic sheds off them in the wash or against your skin.
Thermoregulating
Merino wool is like magic. When you run hot, it cools you down. When you cool off, it holds your warmth. The Lyocell handles the sweat, pulling moisture away so you stay dry.
No Toxic Chemicals
The Lyocell is made in a closed loop process with a non-toxic solvent that's captured and reused. The Merino is non-superwashed, skipping the chlorine and plastic resin coating most wool gets. Nothing harsh against your skin.
Odour Resistant
Naturally antibacterial, Merino stops odours building up without any chemical treatment. You can wear it several times between washes.
Size

Performance fit. Model is 6'0" (183cm) and wears size M.

Temperature range

Intensity

A blend engineered for cool weather training. 75% TENCEL™ Lyocell and 25% non-superwashed Merino Wool. Lightweight, breathable, made for cooler days when a tee isn't quite enough.

Why Lyocell

Made from sustainably sourced wood pulp through a closed loop process. 99% of the solvents used are recovered and reused. Softer than cotton, more breathable than synthetics, fully biodegradable at end of life.

Why non-superwashed Merino

Most Merino wool today is superwashed and coated in plastic resin to prevent shrinking. Our Merino is non-superwashed. No toxic plastic coating against your skin.

Engineered blend

The Lyocell handles moisture wicking and softness. The Merino handles thermoregulation and odour resistance. Together they perform better than either fiber alone, and better than any synthetic alternative.

We believe in full transparency about what goes into our garments. Here is everything that makes up this piece.

Fabric VELM MicroTherm™: 75% TENCEL™ Lyocell by Lenzing, 25% non-superwashed Merino Wool. Top grade Lyocell, produced in a closed loop with no petroleum derived inputs. Non-superwashed Merino, no toxic plastic coating against your skin.
Thread High tenacity polyester. This is the one place we use a synthetic. We tested natural alternatives through development. None passed our tests for stretch and longevity. Thread is what holds the garment together over years, and polyester is the strongest.
Designed in Switzerland Made in China

Built for intense effort in cool conditions. Spring and autumn training, cool mornings, outdoor workouts. Designed to keep you comfortable without overheating.

  • No chafing

  • Printed labels

    Nothing scratching your neck or your stomach while you train. The label is printed directly inside the garment.

Composition
