I got as far as putting it on, on Monday.
I did have a zip-neck base layer, but the instructions should note that it needs to be either zip-neck or scoop-neck (since you will have to reach into the base layer to straighten your b00bs).
The band of my bra didn't seem like it wanted to catch under the HRM. It was really hard to get the right amount of fabric on each side of the bra, so it wasn't pulling on my neck and shoulders, but wasn't bunched up so it would chafe.
It was one of those days and one of those ideas like padding my first MTs, or doing something different to prevent blisters... if it didn't work, I was going to have to cut my run short, and it wasn't a day I wanted to cut my run short. So I took it all back off and put it on the "normal" way.
Since then I've been down with a stomach virus.
I might try it again, but it'll have to be a day I'll be okay with cutting my run short.
