We have covered plenty of cool wearables for kids in the past. Kii and Haltian have teamed up to introduce another kid tracking device called Snowfox. It has voice calling, GPS tracking, and an app. The device has a SIM card and supports two-way calling. It has a weatherproof, impact-resistant design. You can attach the device to a zipper or jacket.
Snowfox will be presented at Mobile World Congress later this month. More information is available here.
