fuwawa Shiki Pad Single Winter Use Ultra-Thick Five-Layer Structure Graphene Filling Aerogel Filling 300g/㎡ Ultra-Thick Cat Touch Fabric Warm Shiki Pad Heat Generation and Heat Retention Material Antibacterial, Odor-Resistant, and Anti-Dust Mite Static Electricity Suppression Washable Non-Shedding 100 x 200cm <Single Black> 【Ultra-Thick Five-Layer Structure】 The shiki pad has a five-layer structure: ① Ultra-Thick Flannel Fabric ② 50% Graphene Filling ③ 50% Aerogel Filling ④ Moisture-Absorbing and Heat-Generating Filling ⑤ Ultra-Soft Waffle Fabric Especially, the ultimate combination of high-tech insulation materials, graphene and aerogel, thoroughly pursues lightness, warmth, breathability, and durability. It exhibits superior heat retention and insulation effects compared to conventional fillings. 【Graphene】 Nobel Prize-winning graphene has the world's No. 1 thermal conductivity. It radiates high-level far-infrared rays through the heat (body temperature) emitted from the human body, exhibiting superior heat retention and insulation effects compared to conventional fillings. You can feel warm from the core of your body just by sleeping. 【Aerogel】 Aerogel filling is an ultra-insulating material that applies space development technology and can insulate against cold air of -196℃ with a thickness of only 2mm. It has the characteristic of firmly insulating against the cold outside air while not letting internal heat escape and allowing only moisture and air to pass through. 【Supreme Touch】 Uses high-quality 300g/㎡ ultra-thick flannel. The ultra-thick and ultra-high-density fluffy nap has a softness like touching a cat's fur and a smooth touch like silk. Please experience the supreme sensation that you can't help but want to stroke. 【Keeps Clean with Antibacterial and Odor-Resistant Processing】 It has been treated with strong antibacterial and odor-resistant processing. The antibacterial effect lasts even after washing, suppressing the growth of bacteria and unpleasant odors even after long-term use.
