Track your activity levels, sleep patterns, and more with the plum Fitbit Alta Activity Tracker in size small. This sleek band uses an array of sensors to keep track of how many steps you take, how far you walk, how many floors you climb, the number of calories you burn, and the time you spend active. It connects to your smartphone via Bluetooth and syncs its data wirelessly while providing you with notifications, workout assistance, and more on its OLED tap display.

The Alta is sweatproof, rainproof, and splashproof, and it uses a flexible elastomer band that fits individuals with wrists measuring 5.5 to 6.7" around.
