This one's been a few times at ETS. I'll repeat what I've said before- get a Wiggy's bag! They can be compressed for years and return to 90% loft with just a good shake. I have three of them and probably won't ever buy another brand unless they change the excellent construction of their bags or I need something lighter than they offer. I don't keep a bag in my truck for driving around town but I always have one along if I'm leaving town, at least in cooler seasons. In SD there's no chance of July getting cold unless we get another ice age!
