I've had a couple mummy
"I've had a couple mummy versions of this pad in the past so really looking forward to having a little more comfort for just a few ounces more in carry weight. So far impressed with the customer service, the timeliness of the shipping, the new winglock valve, the sound reduction from previous version I used, comfort and the size increase. Will be giving it a great test come Sept on 10 day backpack Mt Goat hunt in Alaska."
