Not all fitness bands are waterproof. Thus, you need to ensure that the fitness band you want to purchase is waterproof. Note that, water-resistant is different from waterproof. A fitness band that is water resistant can resist water only to a certain degree, unlike waterproof fitness bands. Otherwise, it won't survive a quick shower, a dip in the pool and a powerful rainstorm. Waterproof fitness bands aren't just a handy tool for your workout, hikes or runs, they are your constant companion during these activities which include swimming and post-workout too.
