Ultra fine merino wool, a rare luxury for skin

Ultra fine merino wool was hand selected by MUUGI as an ideal garment to sit next to skin. Using 14.5 micron (Super 180's) fibers, this extremely soft, jersey stitched merino wool fabric is rarely used in the market.

14.5 micron (Super 180's) is equal to, or finer than, cashmere. Fibers this thin are rare in today’s apparel manufacturing, and used only occasionally in high-end outerwear and shawls. MUUGI’s love for this fine fabric and its non-prickly, naturally smooth features resulted in a one-of-a-kind underwear.

Unbelievably fine. Unbelievably soft. Our merino wool is delicate yet durable and has a natural shine. It is not like common hairy wool, so it is visibly elegant and more gentle on the skin.

Merino wool is naturally insulating. Its thermo-regulating and moisture wicking features keep you cool in hot environments, dry from sticky sweat. It maintains warmth in the cold. It’s a great wear for all seasons. The fibers are antibacterial and odor resistant, so you can wash less frequently. Moreover, recent findings show that merino wool is hypoallergenic, and has a therapeutic effect on those with sensitive skin and eczema.

Cozy up in this rare and versatile underwear this year. It’s supreme comfort you will love.

A wrinkle free, clean silhouette

Ultra fine merino wool is made into a thin, stretchy fabric  so it hides well as an undergarment. It stretches and fits naturally to your body curves. Our sizing takes into account that the fit remains comfortable when wearing a slim top.

The item comes in several variations with different necklines and collars so that you can choose the one that best coordinates with your outfit.

For example, we recommend 2-way Long Sleeve Top under clothes with a large bust opening.
We also chose a collar specification that makes the bumps as inconspicuous as possible.

Crew Neck Long Sleeve Tee is recommended for wearing under tight-necked clothes or turtlenecks. The moderately stuffed neck allows you to feel the comfort of the merino wool fabric down to the neck.

Beautiful to wear as a top

Simple is beautiful. You can wear a merino wool piece on its own. It’s designed to snuggly fit and flatter your figure.
