I saw it was an old post.No, it was not ultralight although it looked good to me. It was probably lighter than I go now.
Go to a closed cell pad like the Z rest. I have a full length Thermarest pad that I have never used other than car camping and a 3/4 length pad which, while comfortable is still too heavy.
I'm not sure what else you could cut on this. I too use the Sawyer rather than a pump and about to phase in an alcohol stove.
Of course I am in New England where both bugs and bad weather should be expected.
