We are debating about what sleeping bags to take for a June 9 departure from Jamestown for the transam. What kind of temps can we expect and where?
We all own 55 degree REI bags that work great for Summer camping. They work pretty well down to 40 if you pile all of your clothes on top of yourself in the bag. It is a real joy to carry only the tiny bags if it is warm enough. We all own some kind of warmer bag as well.
Would a pile liner add more weight than makes sense? Silk?
If there is just a chance of freezing a couple days out of the whole trip maybe an impromptu vapor barrier from trash bags bought locally? Or just get a room if it is colder only a few days?
How cold do we need to plan for and on which sections. It would be nice to have the minimum required for a given section and maybe have something warmer shipped if the place it would be needed was predictable enough. Or do we need to bike the bullet and carry a 30 degree bag?
