Budget determines everything!
If I had an unlimited budget I have have clothing and bags for 10 degree temperature swings...I don't.
I buy for what I have experienced. This is why I carry a 15* F bag in the summer even though I'd like to have a 30* F...I just can't justified $350 for another 900 fill power bag that gets used a few days a year.
Tent...both non free standing and free standing work, I have used both.
Bag...15* F but warmer can work with extra clothing, and I utilize an air mattress for comfort.
Insulation...I have 800 fill power 3 season down jacket.
Bear Canister...Ursack, unless things have changed this year they are legal but you have to take some additional steps to make the safe for use at Trail Camp...experience counts.
10 essentials and personal comfort items. This all fits in 60 L pack comfortably.
