Delara Organic Merino Wool Duvet Insert - GOTS, OEKO-TEX & Woolmark Certified, 400TC Organic Cotton Shell, 500 GSM All-Season Warmth, Baffle Box Construction, Machine Washable - Twin

Our deluxe range of wool duvet inserts uses wool from Merino Wool, which is hand-selected and has full farm provenance. It doesn't matter whether the outside is cool or warm, it will keep you at a perfect temperature. The comforter/duvet insert has a fill weight 200, 300 & 500 GSM which makes soft, warm and lightweight duvet inserts. These are breathable inserts that are naturally grown and also relieve pressure during sleeping because of its lightweight nature. You get two inserts in a box. One will be a 200 GSM summer/spring insert and the other 300 gsm autumn winter insert. You can snap both inserts together using our proprietary method to make a 500 gsm winter duvet insert. You can customize your sleep all year round.

• Triple Certified Organic - GOTS + OEKO-TEX + Woolmark: The only sleep product you'll find with all three certifications. GOTS certifies both the Merino wool fill and the cotton shell - not just the outer fabric. OEKO-TEX confirms zero harmful substances (safe for baby rooms). Woolmark guarantees authentic, traceable wool quality. No synthetics. No greenwashing.
• Built for Hot Sleepers - Wool Wicks, Down Traps: 500 GSM Merino wool naturally wicks moisture away from your body and self-regulates between 65-72°F - the sleep science sweet spot. Unlike down (which holds heat) or synthetics (which feel clammy), Merino responds to your body. Wake up dry. Stay asleep longer.
• 400TC Sateen Organic Cotton Shell - Silky, Silent, Durable: Long-staple GOTS cotton woven into a sateen finish is softer and more tear-resistant than standard percale cotton. No chemical softeners, no synthetic blends. The smooth weave is also completely noiseless - no rustling when you move at night.
• Snap-Together 3-in-1 System + Baffle Box Construction: Buy a 200 GSM insert and a 300 GSM insert, then snap them together via 8 internal tabs for 500 GSM winter warmth - no extra blankets needed. Baffle box stitching keeps wool fill distributed evenly so there's no cold-spot bunching. 8 corner and side ties hold the insert firmly inside any duvet cover.
• Care, Sizing & Small Business Guarantee: Available in Twin, Full/Queen, and King. Shell dimensions run slightly large to allow for a snug duvet cover fit. Dry clean recommended for longest life; gentle hand-wash cycle in a front-loading machine is acceptable for occasional washing - do not tumble dry. Backed by Delara's direct quality guarantee - we're a small, independent business that stands behind every piece.
