About This Product

Premium, white duvet insert with all the features of a standard comforter and the added benefits of organic, natural, luxurious material. DELARA line of wool duvets are made with a certified organic cotton exterior (Global Organic Textile Standard Certified) that effectively manages heat and moisture throughout the night, giving you a cooler, healthier sleep. The fluffy duvet filling is made of 100% pure, hand selected Merino Wool for a breathable, comfortable night’s sleep.

Features

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: 300 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.
Available Sizes: Twin (68"x86"), Full/Queen (88"x92") , King (108"x92")
