Disana Long-Sleeve Wool Sleep Sack

The Disana Long-Sleeve Sleep Sack in Sleeve SleepSack Organic Wool Knit – Jade is crafted entirely from soft organic merino wool. Research shows babies wrapped in wool sleep more deeply, wake less frequently, and show increased alertness when awake. Merino wool's natural temperature regulation prevents overheating while keeping your baby warm all night — no synthetic fillings, no chemical treatments.

Best for: Parents who want a natural, chemical-free sleep environment that helps their baby rest deeper.

Key Features

• Deeper sleep — wool has a natural calming effect that helps babies settle faster and sleep longer.
• Temperature regulating — merino wool adapts to your baby's body temperature, preventing overheating and chills.
• Long sleeves keep arms warm all night
• Snap closure — easy on-and-off at the shoulders.
• Naturally flame-resistant — wool is inherently flame-resistant without chemical treatments.
• GOTS & IVN BEST certified — the highest standard for organic textiles.

Sustainability

Disana uses 100% organic, mulesing-free merino wool — certified to both GOTS and IVN BEST, the highest standard for organic textiles. Every garment is made in Germany with fair labour practices and environmentally responsible production. By choosing Disana, you're choosing natural fibres, traditional craftsmanship, and a company committed to doing right by animals, people, and the planet.

Care

Wool is naturally self-cleaning — air it out and it freshens itself. When washing is needed, hand wash or use a gentle wool cycle at 30°C with a wool-safe detergent. Do not tumble dry. Lay flat or hang to dry away from direct heat. Re-lanolise periodically to maintain wool's natural water resistance.
