FWIW, anyone else trying to smash them down as much as possible, my 0 deg long/wide Wiggys fits in the Sea to Summit XL (10.5 x 23) compression sack just fine and I get the straps pulled down maybe around 1/3 of the way. It might even borderline fit in the next smallest bag but I'm not going to spend the money to find out.
And compressed down like that, it fits perfectly in the bottom of the Paradox 6300 bag.
