Is it any surprise that another sportswear company is getting into the activity tracker game? Well, it shouldn't be. The latest, it appears, will be Under Armour when it launches what the company says will be a "first-of-its-kind performance monitoring system" on February 12.
Under Armour was testing what it appears to be an early version of the E39 a year ago this month. That one, however, was embedded into a compression shirt, while this will be a standalone chest strap device as teased in the video above. Either way, we'll know more in a couple of weeks.
And don't worry, the message didn't really self-destruct, but I will say it's probably one of the best press kits I've ever received. [Under Armour]
