I just bought this bag and have a medium eVent compression sack...will it fit in this sack? Or will I need to get a large?
I'd probably get a large though a medium should work - I use a medium for my pinnacle which is a little smaller. Would you rather have your bag compress to be shorter but fatter (large bag), or taller and skinnier (medium)? That really depends on how you pack your pack. Additionally, are you inclined to put anything else in with it like a sleeping bag liner? Food for thought, regardless those event compression sacks are awesome!
