On an upcoming trip I will have the option of possibly using Trail shelters.
I have never used trail shelters on any previous trips since they weren't available.
I am thinking of using my BPWD Lair and Borah Bivy. Which is a nice setup.
Question is do I need to use the Bivy in the shelters? If so why?
If not should I just leave the Bivy behind and use my Lair and then the shelters when able?
I usually use the Bivy in cooler temps. But don't mind leaving it at home if possible.
