Disana Long-Sleeve Wool Sleep Sack

The Disana Long-Sleeve Wool Sleep Sack in Dusty Blue is made entirely from soft organic merino wool. Merino wool naturally helps regulate temperature, providing breathable warmth while allowing excess heat and moisture to escape. There are no synthetic fillings or added flame-retardant treatments.

The long sleeves offer additional coverage for cooler rooms and seasons. Its roomy lower section gives your baby space to bend and move their legs, while the full-length button closure follows a gentle curve down the front for easier dressing and diaper changes.

Best for: Parents looking for a warm, breathable, natural-fiber sleep sack for cooler temperatures.

Choosing a Size

Disana sleep sacks use European metric sizing. The size name identifies the general size category and is not the exact finished length of the sleep sack.

• Size 60 cm: The smaller size, measuring approximately 25.6 inches from shoulder to hem.
• Size 75 cm: The larger size, measuring approximately 29.5 inches from shoulder to hem.

To choose a size, compare the garment measurements below with a sleep sack that currently fits your baby well. You can also measure your baby from the shoulder to the heel and choose a size that leaves comfortable room below the feet.

The neckline should fit securely and should not be loose enough for the sleep sack to ride up toward your baby's mouth or face. The sleeves should sit comfortably near the wrists without covering the hands. Do not choose the larger size solely for extra growing room if the neckline or sleeves are still too large.

Measurements are approximate and are taken with the sleep sack laid flat. Sleeve measurements are not provided by the manufacturer.

Sustainability

Disana uses 100% organic, mulesing-free merino wool certified to GOTS and IVN BEST standards. Each garment is made in Germany using natural fibers, traditional craftsmanship, fair labor practices, and environmentally responsible production methods.

Care

Wool does not need to be washed after every use. Air the sleep sack between uses to help it stay fresh.

When washing is needed, fasten the buttons and hand wash or use a gentle wool cycle at 86°F (30°C) with a wool-safe detergent. Do not wring, bleach, or tumble dry. Reshape while damp and lay flat to dry away from direct heat. Re-lanolize periodically to help maintain the wool's natural properties.
