Question: is the vivosmart hr waterproof?
Answer: Like the previous Vivosmart, the band is waterproof with a rating of 5ATM, so you can submerge it up to 50 meters, or 164 feet, of water. That means it's safe for swimming. The Fitbit Surge ($199.99 at Amazon) and the Fitbit Charge HR, meanwhile, are only resistant to splashes.
