This is what my husband and I plan on taking for our Wind River trip in August. What do you think? We plan to visit the northern part for 5 or 6 days and maybe go to the southern end for a few days too.I know we have a lot of jackets, but I keep hearing it can snow up there so I'm worried about getting cold. Do you think this is too much? Thanks for your help.
