Old Collection: previous-generation cut. Please check the size chart on this page - sizing differs from the current collection.
There is a base layer you put on and forget about. Not because it does nothing, but because it handles everything quietly: the warmth question, the moisture question, the smell question, all managed by a fiber that has been doing this for centuries. The MERINNOVATION odor resistance women's merino set is that layer. The set includes a long-sleeve top and a full-leg bottom, both cut to layer cleanly under outerwear without adding bulk. The slim athletic silhouette lies flat under ski pants, work trousers, or dress layers without visible seams or bunching.
Worn as a matched system or as separate pieces on milder days, every element of the construction is designed for all-day contact with the skin. Some days begin early and cross several environments. A merino base layer that handles cold morning trails also keeps pace at the gym, looks composed under a professional layer at the office, and arrives at a weekend campsite without drawing attention to itself. The natural fiber carries equal performance through the day's full range, from a still desk start to an active afternoon.
For the woman who needs her kit to work as hard as she does and disappear into the background while doing it, merino is not a luxury: it is the right material for the job. Light enough to move freely, warm enough to carry through a cold morning, natural enough to handle the whole day without intervention. A considered wardrobe means fewer pieces, chosen deliberately, trusted to outlast the seasons they serve. Merino has a reputation for demanding care. The MERINNOVATION set is built for everyday wardrobe use: practical, reliable, and designed to keep performing season after season.
The top and bottom work as a matched insulation system or as standalone pieces on days when only one layer is needed. 100% natural merino provides structure and lasting warmth from a single layer, with no synthetic additives required.

Care Instructions
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 Women's Merino Wool Base Layer Set
The complete base layer, in one box
Matched top and bottom in the same merino knit — for sleep, layering, and travel.

One box. Every base covered.
A matched top and bottom in the same knit — thermals for the slopes, pajamas for cold nights, a first layer for winter travel. Buying the set costs less than the pieces on their own.

Sleep cooler, wake fresher
Merino moves moisture away instead of trapping it, so you don't overheat at 3 a.m. and don't wake up clammy. It's the same reason alpine guides wear it for weeks straight.

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 get the top and bottom separately?
Yes — but the set is priced below the two pieces combined, in the same knit and dye lot so they always match.
Good for sleeping?
It's one of the most popular uses. Merino buffers temperature swings overnight, so you're less likely to wake up hot or chilled.
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.
