Garmin Vivofit 3 and Vivoactive HR

The words "stylish" and "fitness trackers" seldom go together, but Garmin is trying to change that at Mobile World Congress. Its latest wristband, the Vivofit 3, not only comes in a variety of colors but a range of styles, too.

So, as well as the regular version, there are wildly patterned models, and even one with a rippled case, as though you've squirted soft-serve ice cream around your wrist.

The Garmin Vivoactive HR, in contrast, looks far more like a regular digital watch. However, with its bigger display you get a lot more real-estate for data.
