This Mindful Minute fleece was only available to Apple employees who participated in and completed the “Mindful Minute” challenge.
According to MacRumors writer mikedop, who has extensively researched and written about the challenges:
“Those who completed the 2019 Mindful Minute challenge received a soft fleece blanket. The blanket measures four feet by six feet in size (4×6) and contains no designs except for an embroidered mindfulness icon and Apple logo in a light teal.”
The blanket is made from black fleece. For the logo design, the mindfulness icon was simplified to use six interlocking circles in a circle. The design is similar to the Breathe app (which uses eight transparent interlocking circles).
