Hey - I need some assistance. I have a new BIG AGNES ULTRA INSULATED AIR CORE. Although I do not have issues with me blowing it up, I do not want to introduce all my human breath into it and cause pad fiber degradation. The new ones are supposed to be more resistant to that problem. So BA sells a pumphouse: a connecting bag you roll up squeeze open get more air squeeze and so on until the pad is full. My husbands stratus pad has a little tiny foot pump (doesnt fit mine of course) which I really like. Is there something that fits my BA that I havent found yet? The mouth piece for the BA is on the top and is not the size of any others (that I have found)
