My order is being made so I haven't seen any gear in person but am making an order for other gear. I'm trying to determine what size compression sack I need for a Summer Burrow and Summer Incubator packed together. The Burrow is custom and wider at the shoulders tapering to the footbox so I'd say it has an extra 2oz of fill.

I'm guessing either a 15 or 20 liter.

Thanks,
Perry
