I am needing to update some gear. I am looking for a new poncho/shelter setup and I was wondering if any of you have had any experience with the Exped Bivy Ponchos?

I would be using it mostly as a quick rain shelter while hunting and hiking.

Is there a better option that I may have overlooked?

Thanks in advance.
