When I carry the E1e+KL1, I clip it to the inside of my trouser pocket as I would the E2e. The E1e+KL1 is more prone to bezel tipping due to the shorter body retained inside my pocket but due to the secure clip, I've never had it detach without me removing it.
It's also great to clip it to the bill of your baseball cap to make a great 'headlamp' for hands free illumination.
I don't have a pouch for it because I have yet to see a photo of an E1e(+KL1) inside a pouch [that I consider suitable]
