Home Forums Hunting & Shooting Backpack Hunting Sleeping bag for backpacking in Colorado October

If you are going to be at high elevations, plan for it to be cold.

I backpack hunted in September in Colorado last year. I was camping at 10,000' and I used a +4F bag (Kelty Cosmic 4). I wasn't cold at around 28-35 degrees but I wasn't super warm either. I get cold easily, though, when I am not moving. If I was going in October, I'd have a sub-zero bag with me.

I have not read the whole thread but you obviously have a decision to make on insulation material. Down is obviously more compressible but the synthetic is warmer when damp. I have a North Face Inferno -20F down bag that I use in subfreezing backpack hunts in the North East and it gets damp and icy from condensation after a couple nights. On longer trips, I deal with the weight of one of my synthetic bags. Moisture is probably less of an issue out west though.
