Class A Cotton Silkworm Pupa Protein Zipper Duvet Set – 2-in-1 All-Season Comforter (Summer + Spring/Autumn Layers Combine for Winter)

2-in-1 Zipper Design – One Set for All Seasons
This innovative duvet set consists of two separate comforters: a lightweight summer quilt and a thicker spring/autumn quilt. Use them individually for warm or mild weather, or zip them together as one cozy winter duvet. The smooth, full-length zipper makes combining and separating effortless.

Class A Cotton Shell – Safe for Babies & Bare Sleepers
Crafted from premium Xinjiang long-staple cotton, the outer shell meets stringent Class A safety standards (infant-safe). It is completely free from fluorescent brighteners, formaldehyde, and other harmful substances. Soft, breathable, and gentle on even the most sensitive skin.

Silkworm Pupa Protein Fill – Nourishing & Temperature-Regulating
The fill is made from advanced silkworm pupa protein fiber, which contains 18 amino acids to help nourish and hydrate skin while you sleep. The unique porous structure provides excellent thermal regulation: it reduces heat conduction in cold weather and releases excess heat in warm weather, keeping you comfortable year-round.

Breathable, Lightweight & Non-Pressing – Superior Comfort
The hollow fiber structure makes this duvet 1.5 times more breathable than cotton and 1.8 times more moisture-absorbent than wool. It feels lightweight yet warm, never heavy or stuffy. The even fill distribution and circular quilting prevent shifting, ensuring consistent comfort night after night.

Thoughtful Details – Easy to Use & Maintain
Features color-contrast piping for a clean, modern look. Small corner loops keep the duvet securely attached to your duvet cover, preventing bunching. Machine washable on a gentle cycle for easy care. Available in multiple sizes and weight combinations to suit your needs.
