Phone armbands - recommendations

what are some recommendations for sweatproof armbands to carry (workout) a phone to listen to streaming music, books on tape, etc

I bought one that was a slim sleeve and then quickly realized that it is not water/sweatproof

Many of the ones I see on Amazon looks big/bulky

For a Galaxy S10
.

I like the Quad lock system. Can easily be moved from bike to arm band etc.

I like to leave the phone at home.

I have been using Tune Belt arm bands. They work with pretty much any kind of case; just buy the right size. Not the easiest if you need frequent access to your phone, but I just need the phone with me. Also not 100% water and sweat proof, though my phone comes out pretty dry.

I use the Nathan StrideSport for my iPhone 7 Plus https://www.nathansports.com/collections/gear/products/stridesport-smartphone-carrier?variant=20448640827480

This, but a phone maybe need for emergency. An arm band will lead to poor assymetrical run mechanics. A fitbelt is better because it is centered on the body

LOL what?

They ran faster so they can listen to music at home sooner.

I carried around some coins in case I needed to use a pay phone to call for a ride, as well as a $20 bill for emergency cab fare. Now there are no pay phones to be found in my area.

I use THIS ONE from Nathan. It’s not waterproof but it never gets wet enough inside to damage my phone (iPhone 8).

Also, I’m pretty sure you don’t have to worry too much about an armband affecting your run mechanics.
