The Mooncastle Cashmere Bottleneck Pullover is a true expression of Japanese knitwear excellence, crafted from 100% premium cashmere, often referred to in Japan as “the jewel of fibers.” This exceptional piece is produced by Mooncastle, a factory brand launched in 2020 by a historic knitwear manufacturer founded in 1966 in Misaki, Osaka Prefecture, a quiet coastal and mountain town in the south of Osaka. With very few exceptions, all Mooncastle products are made entirely in their own in-house factory, ensuring uncompromising quality and consistency.

This cashmere knit is one of the brand’s most anticipated winter pieces—offering an extraordinary balance of silky softness, natural warmth, and luxurious comfort. The texture has a rich, slightly creamy handfeel unique to high-quality cashmere, providing exceptional insulation while remaining breathable. Thanks to the natural oils on each ultra-fine fiber, the fabric feels smooth and supple against the skin and is perfectly suitable for sensitive skin. The low thermal conductivity of cashmere allows it to trap warm air efficiently, while its high moisture absorption keeps the body warm without overheating or feeling stuffy. The natural luster of the fiber adds a subtle, refined sheen that synthetic materials simply cannot replicate.

The knit is constructed in a mid-gauge 7-gauge structure, giving it real substance and presence. The surface uses a textured half-rib stitch, creating beautiful depth and volume while maintaining a clean, elegant look. Unlike lighter jersey knits, this method minimizes pilling and excess fuzz, preserving a sharper appearance over time. The fulling process (which normally increases the fluffiness of cashmere) has been intentionally kept to a minimum. Mooncastle’s philosophy is to allow the garment to soften naturally over years of wear and washing, gradually becoming even more luxurious with age—true to the idea of a lifetime sweater.

The fit is a regular, balanced silhouette—neither slim nor oversized—designed to work effortlessly on its own or as a refined layering piece. The slightly elevated bottleneck (mock neck) provides warmth while maintaining a clean, modern profile. Ribbed cuffs and hem offer gentle structure, keeping the sweater neat at the wrists and waist without restricting movement. For those who prefer a relaxed look, sizing up one or even two sizes is also a great option for a more laid-back silhouette.

The cashmere yarn itself is supplied by Toyoboshi, one of Japan’s most prestigious spinning companies and the very first to produce cashmere yarn domestically. Founded in 1879, Toyoboshi has more than 130 years of history and over 80 years dedicated specifically to cashmere spinning. Their Japanese-made cashmere yarn is internationally recognized for its consistency, purity, and exceptional quality, preserved through generations of master artisans and advanced proprietary technology.

What makes this pullover especially remarkable is its rarity: a mid-gauge, heavyweight 100% cashmere knit, fully made in Japan, at this level of construction and finish. Even by global standards, this combination of material quality, weight, craftsmanship, and price represents extraordinary value for what is truly an heirloom-grade garment.

Fit Notes: Mooncastle garments tend to run slightly smaller than standard American sizing. We recommend choosing one size up from your usual American size. For example, if you normally wear a size M in American brands, selecting a size L will provide the best fit. As always, we recommend consulting the size chart to ensure the perfect fit.
