Enjoy continued peace of mind from your Smart Sock 3 with the Owlet Extension Pack.
The Owlet Extension Pack allows you to continue tracking your child’s heart rate, oxygen level, and sleep trends up to 5 years of age. The included toddler-sized fabric sock works with your existing Sock 3 sensor, and our optimized technology continues to provide accurate readings as your child grows, between 13kg to 25kg.
Continue to monitor your child through every milestone—from teething to toothfairy.
