Used WHOOP 3.0 and 4.0 wearable technology. Comes with a new white band, a black band, charger, and cords.Bands are compatible with both versions.All you need is a WHOOP membership that you purchase online and the WHOOP mobile app in addition to these physical products. After purchasing those you will have everything you need to start tracking your health.Loved the WHOOP - only reason I am selling is because I switched to the Oura ring.
