Frequently Asked Questions
Is 5ATM better than IP68 for swimming?
5ATM is generally a clearer swim-ready rating — it’s designed to withstand pressures equivalent to a 50m depth and is typically suitable for pool and open-water swimming. IP68 indicates protection against dust and immersion but testing specifics can vary by manufacturer; check product details if you plan frequent open-water sessions.
Can I wear a smart ring while cycling in heavy rain?
Yes — swim-rated (5ATM) rings and well-sealed IP68 wrist trackers handle rain and heavy sweat. The main concerns are fit (the ring must maintain skin contact for accurate sensors) and avoiding unnecessary impacts or abrasions during falls.
How important is sizing for smart rings?
Very important. A ring that’s too loose will produce poor sensor contact and inaccurate readings; too tight will be uncomfortable, especially during extended rides when fingers can swell. Use a sizing kit or manufacturer guidance before buying.
