Sierra Wool Maxi Sleep Bag – natural warmth that grows with your child
Colour: beige
Size: 0–36 m
Wool type: premium wool
One sleep bag for three years? With the adjustable Maxi Sierra, it's possible. Premium sheep's wool with a double fleece layer naturally regulates warmth – keeping your baby cosy when it's cool and wicking moisture away when it gets warmer. The wool helps keep your little one comfortably warm without overheating, whatever the weather.
The adjustable length (92/110 cm) allows you to adapt the sleep bag to your growing child's height, while the universal harness slots ensure compatibility with a wide range of prams and car seats. Maxi Sierra is an investment that lasts throughout the infant period and the early years of childhood.
Every sleep bag is hand-sewn in Poland, with the same care with which you wrap your child.
Why you'll love the Maxi sleep bag:
Premium wool
High-quality sheep's wool with a soft fleece on both sides of the knit, providing better insulation than regular wool while wicking moisture away effectively. It thermoregulates naturally – warming without overheating. Hypoallergenic and self-cleaning, it is resistant to dust mites and neutralises odours.
Frequently asked questions
How does the length adjustment work?
The sleep bag can be set to 92 cm (for younger children) or 110 cm (for older children). This means one product lasts from birth to approximately 3 years of age.
Does the sleep bag fit a car seat?
Yes – the universal harness slots ensure compatibility with prams, carrycots and car seats alike.
What is the difference between Maxi and Mini?
Maxi has an adjustable length (92/110 cm) and is suitable up to 36 months, while Mini (90 × 40–42 cm) is designed for children up to 18 months. Maxi is the longer-lasting choice.
How do I care for the sleep bag?
Wool is self-cleaning, so airing is usually all that is needed. If necessary, we recommend careful hand washing at max. 30°C using a wool detergent. Do not machine wash, do not spin, do not tumble dry – dry flat.
Composition
Fleece (in contact with skin): 100% wool
Total product composition: 70% wool, 30% polyester
Polyester serves solely as the structural base (load-bearing mesh) on which the natural fleece is anchored.
Care
Hand wash at max. 30°C with a wool detergent, using the same temperature for washing and rinsing. Do not machine wash, do not bleach, do not iron, do not spin, do not tumble dry or place on a radiator. Dry flat. Gentle dry cleaning is permitted. Loose fibres on the surface are a natural characteristic of fleece products – before first use, air and shake the item; during use, brush gently with a soft-bristle brush. The natural smell of wool fades after airing.
