I normally carry my puffy in a nylafume bag for quick easy access.Found a pin hole in it with the inflation method last night.The problem is when I tested my other bags I can only effectively test about half the bag by the time I get it inflated and twisted down to compress the air etc.So I'm going back to my OR pack liner which weighs a whopping 3.8 oz but considering the alternative it could be priceless.
