We live in CO. We currently have heavy 0 degree bags which work just fine for winter and car camping. However we're preparing for an 09 backpacking trip and I need to get a 20 degree bag for my son. He is 13, probably pretty average for a 13 year old in terms of responsibility, having a broken brain, etc. :-)
I'm struggling with the down vs. synthetic decision. I know all the pros and cons. I'm interested in getting some real world, "on average" types of input such as "Boy - I've seen some scouts really get in trouble because they weren't diligent enough keeping their down bag dry." or "The extra weight and size of synthetic is more than a reasonable price to pay to ensure they can keep warm.", etc.
Any words of wisdom?
Thanks.
