Perhaps someone who has experience with Downmats can shed some light on this.
I am thinking of getting the new Exped Downmat UL7. I would be using it for all seasons (I'm a very cold sleeper). My hesitation is that I live in the Pacific Northwest so I can count on getting at least light rain on every trip, and the air, while not necessarily humid, is not dry. I'd use the schnozzel to inflate, but I don't know whether it would just be a silly idea to use a downmat here, outside of winter use.
Have any of you downmat-users used your downmat in rainy climates, and did this seem to affect its performance?
I thought I'd find lots online about the rain+downmat configuration, but haven't yet. If you already know of a place where this discussion has happened, feel free to send me there instead.
My other option is the Xtherm, which is significantly lighter and probably more rain compatible. When I was testing them both together in-store, the shape of the downmat made it so much more comfortable, which perhaps would equate to a better sleep for me; and it was so much less noisy, which would probably be appreciated by tent-mates when applicable.
Thanks for your thoughts!
