Re: Using a compression sack to pack clothes
All of that and the laptop should fit in a Marauder with no problem. I just did a 3 day trip to the in-laws with my XRay (which has the same "beavertail" opening) and fit than much and my Vasque Sundowners and a pair of cap toe oxfords for church. With the Marauder, fold stuff so items are the dimensions of the panel that's against your back, and stack. Sandwich the laptop between layers, then pile in the small stuff.
I don't think a compression sack saves room with clothes, short term for sleeping bags and stuff, but flat folding or rolling for clothes is your best bet...
