A sleep sack promotes safe sleep by eliminating loose blankets and regulates body temperature for comfortable and uninterrupted sleep. It simplifies the bedtime routine and reduces the risk of SIDS, making it a must-have for any parent.

SIJO's CLIMA technology is a German engineered fiber technology that helps regulate body temperature during sleep. It is made of an advanced phase changing lyocell fiber which is both highly breathable and moisture-wicking. This technology works by creating a microclimate between the sleeper and the bedding, which allows air to flow and heat to dissipate. This helps prevent overheating and sweating, which can disrupt sleep and cause discomfort. The CLIMA technology also helps maintain a comfortable temperature throughout the night, promoting deeper, more restful sleep. Overall, SIJO's CLIMA technology is a game-changing innovation in sleep technology that helps ensure a comfortable and restful night's sleep.

TENCEL™ lyocell is a type of sustainable fabric made from the wood pulp of eucalyptus trees. It is produced using a closed-loop process, which means that the solvents used in the production process are recycled and reused, minimizing waste and reducing environmental impact. TENCEL™ lyocell is known for its softness, durability, and moisture-wicking properties, which make it ideal for use in baby's bedding, clothing, and other textile products. It is also hypoallergenic and gentle on the skin, making it a popular choice for babies with sensitive skin. Overall, TENCEL™ lyocell is a sustainable and eco-friendly alternative to traditional fabrics that offers a range of benefits for both consumers and the environment.

Yes, our sleep sacks are designed to allow babies to move their arms and legs freely while still providing a secure and snug fit. The sleeveless design and generous fit allow for full range of motion, which can be important for a baby's development.

It is not recommended to use a baby sleep sack in a car seat or stroller as it can interfere with the proper fit and function of the restraint system. When traveling with a baby in a car seat or stroller, it is important to follow the manufacturer's instructions and use only the accessories that are designed and tested to be used with the product. Using a sleep sack or any other unauthorized accessory can compromise the safety of the baby in case of an accident or sudden stop. Additionally, using a sleep sack in a car seat or stroller can increase the risk of overheating, which can be dangerous for babies. Therefore, it is best to reserve the use of a sleep sack for bedtime in a safe sleeping environment, such as a crib or bassinet.

The Joi sleep sacks can be machine washed on a gentle cycle using a mild detergent and cold water. It's important to avoid using harsh detergents, fabric softeners, or bleach as these can damage the fabric or irritate the baby's skin. It's also a good idea to wash the sleep sack separately from other laundry items to avoid snagging or tangling. After washing, the sleep sack can be dried on a low heat setting in the dryer or air-dried flat. By following the care instructions and taking proper care of the sleep sack, you can ensure that it stays clean, fresh, and in good condition for your baby to use.
