a comforter model is introduced


A new evolution in blankets
brought together in an
advanced infrared blanket

Proprietary newly developed material
MEDIC
RECOVERY
FIBER
A ceramic material made from natural minerals found on Earth. Among them, high-purity ceramics are carefully selected and blended using a proprietary formulation.
High-level far-infrared emission is achieved through high-density nano-level processing applied to the fibers, along with a specially designed yarn structure.

ISSUE
Different home environments mean
different insulation needs.
Differences in airtightness between apartments and detached houses, as well as variations in housing performance and building age, lead to different bedroom temperature conditions.
It is said that depending on a home’s level of airtightness, perceived temperature can differ by as much as 5°C.
A versatile solution
for diverse living environments
Your bedroom stays warm — so a blanket or lightweight comforter is all you need, even in winter.
You want a blanket or lightweight comforter to adjust to temperature changes throughout the day.
You're looking for a blanket that lasts for years to come.
Adopts advanced far-infrared technology
Recovery blanket

Carefully selected ceramics at the nano scale are blended from multiple types.
Through proprietary processing, a high concentration of ceramics is successfully integrated into the fibers.
In addition, a specially engineered yarn structure enables a high level of far-infrared radiant heat.
Developed from the ground up with recovery in mind, the yarn and fabric are engineered to efficiently absorb body heat and re-emit it as far-infrared radiation back to the body.
Supports comfortable sleep by helping maintain an ideal in-bed temperature of 33 ± 1°C and humidity of 50 ± 5%.
In cold winter conditions, simply placing it beneath your existing comforter can increase temperature by up to 6°C.
By supporting an ideal in-bed temperature of 33 ± 1°C, it helps maintain a comfortable sleep environment.
The cashmere-blend side offers a smooth, refined feel that goes beyond cashmere-like materials, while the cotton-blend side provides a light, breathable texture with a clean, comfortable finish.
In addition to being machine-washable,, enhanced sterilizing performance helps suppress bacterial growth, maintaining a clean condition day after day.
※For a single size, a washing machine with a capacity of 7 kg or more is recommended. Please refer to the washing machine’s instruction manual before laundering.
When not in use, it can be stored compactly in the included drawstring bag.
Easy to carry and convenient for outdoor use as well.
Through its advanced fiber structure, this winter-use cashmere blend reproduces the scale-like fiber structure found in cashmere and wool, which is known for excellent moisture absorption and release.
The result is a breathable, non-stuffy sleep environment with high moisture regulation. Moisture is further converted into heat, delivering exceptional warmth.
Functions
Far-infrared radiant heat
Thermal insulation
Moisture-absorbing heat generation
Moisture absorption and release
Highly absorbent cotton is incorporated in the pile layer. While maintaining the light, refreshing feel unique to cotton blends, it also delivers comfortable warmth.
Ideal for transitional seasons such as early autumn and spring.
Functions
Far-infrared radiant heat
Thermal insulation
High absorbency
By absorbing and releasing moisture across the entire blanket,
a stable and comfortable in-bed humidity environment is maintained.
Even over time, the ideal in-bed humidity of 50 ± 5% is preserved.

An ultimate thermal blanket
for winter comfort
Yes, the product can be machine-washed at home.
Please place it in a laundry net and wash separately.
Avoid using bleach (chlorine- or oxygen-based).
No. Tumble drying may cause shrinkage or deterioration.
Line drying in the shade is recommended.
The product features a reversible design and is suitable for home washing, allowing use without a cover.
No cover fasteners are included.
The comforter features a reversible design.
Both sides are blanket fabrics: one side is designed for winter use, and the other offers a softer cotton feel suitable for autumn and spring.
This is a lightweight blanket-type comforter with an approximate thickness of 2 cm.
The reversible design allows use according to the season and personal preference.
For winter use, the cashmere blend side is recommended against the skin, while for spring and autumn, the cotton blend side is recommended.
Thin comforters may lose their loft if stored in compression bags for extended periods, so this is not recommended.
For storage, place the comforter in the included fabric storage bag and keep it compactly stored.
Available in a single brown color option.
