Description
Alessio Set | Extra-Fine Merino Wool | Castielli
The Alessio Set pairs a knitted top and matching trousers, knitted in pure extra-fine merino wool. Merino breathes and holds warmth without bulk. It also resists odor, so one set covers a long flight, a slow Sunday and dinner out without a wash in between.
Why you'll reach for it
- Pure merino: extra-fine fibers with none of the itch of standard wool
- Temperature control: insulates outside and breathes indoors, wearable most of the year
- Matched by design: top and bottom come from the same yarn and dye lot, so the pairing always reads intentional
- Fewer washes: merino resists odor naturally, so it needs less laundering than cotton
- Quiet finish: no logos and clean lines, nothing that dates or shouts
Fit and fabric
Both pieces follow EU sizing. The top has a relaxed drape that never clings, and the bottoms sit clean through the leg with room to move. Sizes are selected separately for top and bottom, so an M top can pair with an L bottom if that matches your build. The fine knit stretches with you and recovers its shape.
Care
- Machine wash cold on a wool cycle, 30 degrees max, or hand wash
- Dry flat away from direct heat, reshape while damp
- Store folded, never on a hanger

Care Instructions
Care Instructions
Hand wash cold or use the wool cycle, then dry flat rather than on a hanger so the shoulders keep their line. Lift any pilling with a cashmere comb once a season. Between wears, air it overnight instead of washing.

The Fibre
Cashmere and extra-fine merino
Cashmere traps air instead of adding weight, which is why a thin crewneck outperforms a thick one. Extra-fine merino handles the days that start cold and end mild, and takes several wears between washes. Both are knitted to a weight you can layer under a coat without bulk at the shoulder.
The Knit
Ribbing that springs back in February
Cuffs and hem knitted tight enough to hold after a season, seams finished on the inside, and a neck that lies flat instead of rolling. The parts you only judge on the tenth wear.
