Great review, very thorough!
Reminds me a lot of the Chrysalis. Including weight. Looks very comfy.
I guess it does not have a pad pocket, neither does the older Chrysalis. If there was a pad pocket dbl layer, it would probably work just as well with a pad as the BMBH does.
Clearly you would need a separate tarp to keep an UQ dry, if you can get an UQ to fit OK.
Thanks for the god info!
