Just curious what low temperatures to expect/prepare for on a NOBO on the CDT with a mid April start. Research seems to say low to mid 20s. Any experience or advice. I know that there could be colder days, but can handle a few nights outside the norm. Advice appreciated. My gear has worked OK down to 15-17 degrees.....cold night but not miserable. Just wouldn't want to do it a lot without warmer gear.
