LPP and Puffy Pants Stuff sack size?

[HoytHunter24]

I have a medium hooded Kifaru Lost Park Parka and a pair of Blackovis puffy pants I am trying to find a stuff sack for. I have been looking at the Kifaru 3 and 5 string compression sacks but I am not sure which one with fit both garments together.
I asked Kifaru’s customer service and they recommended a 5 string Large bag. I think that may be too big.
Does anyone have experience with this? What would you recommend?
