The material is nice and soft, brushed feel. It's over the spec weight. Mine is mummy one, and it's 256g with the storage bag. I bought it with the mini pump, which is about 80g. Works ok, and rechargeable. You can blow it up with relative ease, not so sure about breath-inflating in general. I may have a different valve than
