Athos activity tracker review

Most activity trackers, while fully featured, can be a little limited by their location. Tracking your wrist is great for distance travelled and calories burned, but it doesn’t do much if you’re pumping heavy iron on a bench. How then can we solve this issue? The Athos fitness tracker believes it has it figured out, by putting the sensors in the clothing, rather than in the tracker itself.


The Athos fitness tracker system is made up of two key components, the core, which contains all the computational components and the battery, and the compatible article of clothing which features all of the sensors in select locations. Unlike most wearables which attach to an appendage via a strap of some kind, Athos can be attached to a compression shirt or pair of shorts, each filled with a number of different sensors. These sensors are strategically placed to give the Athos access to reams of data that other workout trackers do not.

The core itself features a battery life in excess of 10 hours, so even the most strenuous of workouts will be no challenge for it to track in its entirety. It’s also tiny, measuring in at just 2.5 inches tall and weighing in at just 20g, you’ll hardly notice it.

The shirts and shorts allow full tracking of a number of different muscles at any one time, along with heart rate and breathing patterns, letting you see how intensive training affects you on a day by day basis and therefore, how you improve over time.

The sensors in the clothing are built in and therefore require no straps or adhesives. They remain in contact with the skin thanks to the compression shirt material, which conforms to your body shape. They’re also breathable and sweat wicking, keeping you as cool as possible under the circumstances.

They’re even machine washable.



While you can’t buy one of these outfits and sensor suits yet, the Athos core and clothing combination will cost around $400 for a complete set. The shorts and shirt individually are $100, while the core will set you back $200. The minimum expenditure in this scenario is $300 (£178) for basic functionality.


The Athos is a pretty expensive bit of kit. If you’re just looking to track yourself running or swimming, it is far more than you’ll need too. It’s pretty high end as far as activity trackers go, so it could struggle to find a place among all the budget offerings.

Bottom Line

While premium products like this are going to struggle too compete against the more economic products, that doesn’t mean I don’t want one. Out of all of the wearables we’ve looked at for tracking fitness, this one seems the most comprehensive. If you have the money and want the best out there (soon), then the Athos could be the right choice for you.
