I have a new yukon yak w/ the optional cargo fly. I'm concerned about packing my down sleeping bag or other down garments in the drybag inserts since they must be inflated by mouth, and I want to avoid having these items sit in moist air all day and absorbing the moisture from my breath and losing insulative qualities during the trip. Has anyone figured out a DIY adapter for the inflation bag that would work on the dry bag mouthpiece inflation stem? or some other solution? can't seem to find anything posted about this but I have to imagine i'm not the first to consider this issue. Thanks in advance for any responses / feedback !Jun 28, 2013 at 2:48 pm #2000594

doesn't yer stuff just go the cavern, and then you pump up the raft, so the container area gets smished ?
i dunno .. that's how it looked to me on their website.

um…not sure i understand the comment but no you are supposed to inflate both the raft as well as the dry bags. anyone on the forum who has one and can comment?Jul 3, 2013 at 12:35 pm #2002141
You might find some useful info in the comments of this thread I started on modifying Alpacka inflation bag to inflate a neo-air. http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/thread_display.html?forum_thread_id=75655Aug 16, 2013 at 1:58 pm #2015875

el, the down in your sleeping bag and garments do have a dwr shell over them so I'm not sure if breath condensation will do too much harm if any. especially if you are expressing air as you create the airtight seal. dont know for sure. maybe test it out at home or someone more qualified with experience can chime in.
also, I have an extra instaflator if u need it buddyAug 18, 2013 at 6:54 pm #2016430
I'm not sure how they're actually intended to function, but since these bags go inside of the inflated raft, they wouldn't need to be fully inflated unless you were counting on them to act as some sort of redundant floatation measure (boats are required in some areas to have 3 chambers). I presume – perhaps incorrectly – that 95% of the time you would just add your stuff and close the drybags without topping up the air.
In situations where you do top up the drybags by mouth, I imagine most of the bag would be inflated just by virtue of filling it with stuff, so you're probably only dealing with a breath or two of moist air (pure speculation). That's not much and I suspect only on long damp trips would it be a potential problem. In this situation, you could store your sleeping bag inside of another dry bag inside the alpacka drybag. For example, store your sleeping bag in a 1oz silnylon roll top dry bag, toss that in the Alpacka dry bag along with the rest of your gear and then top up the air as needed.
