I returned this product before using it
This is the most bomberest of bomber flannels I have ever seen. The fabric is super heavy. I wouldn't want to wear this other than bike riding and cutting lumber. I returned it because it was a little much for what I wanted it for.
The option to switch between left and right entry is a plus. It feels well made and works great on my ibis mojo 3 with a 24 out camel back podium bottle. This also works better at holding http://www.backcountry.com/lezyne-flow-sl-cage.
