The new sea to summit pads are amazing. I spent 4 hours in rei a few weeks ago trying out EVERY pad they had. No question the seas to summit was most comfortable. I also loved the valve design as it inflates and deflates almost instantly. I also liked the dual air chambers both for adjustable comfort and in case one side is punctured you aren't laying on the ground.
If I'm willing to carry a few extra ounces anywhere it's for a sweet sleeping pad.
Is there a specific sea summit you all recommend for cold cold nights?
Pretty fond of my exped LW ul9. Worth the weight IMO.
