What Make Joi Unique?
Science Backed
SIJO’s CLIMATM technology makes up the fibers of the sleep sack’s inner components. These fibers help regulate temperature by absorbing and releasing heat, keeping baby comfortable all night, and in all seasons.
Natural Materials
TENCELTM knit exterior and outer elements are buttery soft to envelop baby in coziness. This is also a natural, sustainable, and extremely safe material boasting breathable and hypoallergenic benefits giving parents peace of mind.
Design Details
Thoughtful elements are in the details. Each sleep sack features double shoulder snaps for easy wear and removal as well as double zippers that are enclosed and that have zip guards to keep baby safe. A helpful, brightly colored exterior tag helps showcase where the side zips are located, allowing parents easier access for nighttime changes.
Impact of Temperature
Most baby sleepwear items are measured by a TOG number (this indicates the material thickness needed for safe sleep based on room or outdoor temperatures). Many brands offer products with different TOG for different seasons.
What makes JOI different? One of our sleep sacks can work for almost all seasons (especially for TOGs 1., 1.5, 2., 2.5), making it an economical and eco friendly option compared to other brands, which require the purchase of multiple sleepwear products for different TOG ratings. Because these are meant to be worn with pajamas, one JOI sleep sack will work with a short sleeve onesie in the summer, and a long sleeve onesie in winter.
Founding Story
FAQs
Why baby products?
With SIJO, we’ve created sleep products that work perfectly for most of the family. We want to bring better sleep to baby and allow parents to rest well knowing their whole family is enveloped in safe, healthy, products.
Why a sleepsack not a swaddle?
Part of our mission is sustainability and reuse. Sleep sacks are increasingly popular, and they last beyond the period of the swaddle, which is mainly for newborn and early infant stages. Sleep sacks can be used for toddlers up to age two. We may consider swaddles in the future!
Do sleepsacks come in more than one size?
Yes, they do! Our Sleep Sacks come in varying sizes to accommodate multiple growth stages for baby.
Co-founder Anni Stromfeld started SIJO alongside childhood friend Jacob Xi after reconnecting and bonding over their common interest in entrepreneurship and a desire to build an ethical and sustainable business in the health/wellness area. Her vision was to transform the way consumers think and feel about the home.
After working in high-stress, results-driven work environments and juggling her career and personal life, she sought to find balance in the chaos of life. The root of that: better, healthier sleep. This journey to find balance helped her (and Jacob) precisely identify the demands of the SIJO customers, using innovative fibers and materials to create the best possible products.
Anni, Jacob and their team focus on creating sustainable, performance driven products that not only boast healthy benefits and unparalleled quality, but that have a simple, modern aesthetic that suits any home.
