140 g/m²
Light & very breathable: summer, high cardio, active base layer.
Merino wool
Merino wool
Natural, efficient, and comfortable in every season: discover why merino is the reference technical fiber for sports and everyday life.
Why choose merino?
- Active thermoregulation
Merino helps stay in the comfort zone during effort/rest phases thanks to dynamic breathability and better heat/moisture management.
- Moisture management
Hygroscopic fiber: absorbs water vapor then releases it gradually, limiting the "wet" effect and chills.
- Natural anti-odor
The protein structure (keratin) and fiber architecture reduce odor buildup: ideal for multi-day use.
- Comfort & softness
Fine fibers (low microns) for a soft touch, even on sensitive skin.
- Responsible
Certifiable supplies (e.g. RWS) covering animal welfare, land management, and traceability.
Useful facts & figures
| Property | Value / Info | Why it is useful |
|---|---|---|
| Thermoregulation | Measured advantage in dynamics (effort ↔ rest) | Fewer hot/cold spikes, stabilized comfort during "stop-&-go" activities |
| Hygroscopicity (regain) | ≈ 11–16 % Water at standard conditions (can go well beyond without feeling wet) | Absorbs vapor, limits condensation on the skin |
| Absorption before wet feeling | Up to ~35Â % of its weight | Remains comfortable in cold and humid conditions |
| Odor | Natural reduction of odor buildup | Allows multi-day wear (trek, travel, bikepacking) |
| Recommended care | Wool cycle 30–40 °C, wool detergent, gentle spin, flat drying | Preserves fiber and fit over time |
| Certification | RWS: animal welfare, land management, traceability chain | Ensures responsible practices from the ranch to the finished product |
Recommended weights & uses
210 g/m²
Warm/moderate: winter, bivouac, layering under a shell.
300 g/m²
Very warm & insulating: extreme conditions, high mountains, minimal shower use.
Tip: adjust according to your cold tolerance and effort intensity.
How does merino regulate?
- Sorption heat: by absorbing water vapor, the fiber releases a small amount of heat that limits sudden cooling.
- Capillarity & scales: complex structure promoting vapor evacuation and resilience (deformations ↔ shape recovery).
- Keratin & pH: environment less conducive to persistent odors compared to some synthetics.
Simple care
- Turn the garment inside out and use a wool cycle 30–40 °C with wool detergent.
- Gentle spin, no fabric softener, avoid tumble drying.
- Flat drying, away from a heat source; air out between wears.
Ethics & traceability
We prioritize traceable supply chains, mulesing-free and recognized certifications (e.g. RWS) that oversee animal welfare, pasture management and the traceability chain.
Depending on the collections, the origin areas and batches may vary.
Frequently asked questions
Does merino itch?
Fine fibers provide high softness. An initial wash can optimize comfort for ultra-sensitive skin.
How many days without odor?
Depending on the effort and ventilation, several consecutive days are possible thanks to natural antibacterial properties.
Which thickness to choose?
140 g/m² (summer/cardio), 210 g/m² (winter/layering) or 300 g/m² (extreme conditions).
