Full description:

The Mooncastle 7G Cashmere Bottleneck Pullover is a true expression of Japanese knitwear excellence, crafted from 100% premium cashmere — a fiber 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. With very few exceptions, all Mooncastle pieces are made entirely in their in-house factory, ensuring uncompromising quality and consistency.

The cashmere 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 brings more than 130 years of history and over 80 years dedicated specifically to cashmere spinning — its Japanese-made yarn internationally recognized for consistency, purity, and exceptional quality, preserved through generations of master artisans and proprietary technology.

This is one of Mooncastle'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, suitable even for sensitive wearers. The low thermal conductivity of cashmere traps warm air efficiently, while its high moisture absorption keeps the body warm without overheating. 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 appearance. Unlike lighter jersey knits, this stitch minimizes pilling and excess fuzz, preserving a sharper look over time. The fulling process — which normally increases fluffiness — has been intentionally kept to a minimum, allowing the garment to soften naturally over years of wear and washing, gradually becoming even more luxurious with age. A true 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.

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: This pullover runs small. Compared to most global American brands, we recommend sizing up one from your usual size for a comfortable fit. As a reference, we strongly recommend checking our size chart and comparing it with your best-fitting sweater to ensure the right fit.
