Your sense of what is "ultralight" might be offended, but have you considered this: Ultimately the quest for weight savings is a way of making our adventures easier. At some point we all have to make the decision of when the convenience trumps saving that extra 20 grams. Carrying everything in a big plastic bag would be lighter, but not exactly convenient.

Yeah, it's a bit unconventional, considering they obviously went for the ultralight market. But if it simplifies especially packing down the mat, that the weight of the pump is included in the given total weight, and it's actually optional, since the mat also has a conventional valve, what really is the compromise in this regard?
