Sleeping bag for an Oregon mountain
I'm having some analysis paralysis here and need advice from experienced campers. Should I get a 20 or 35 degree sleeping bag for this situation?
Immediate use: DD1, age 17, is doing a weeklong Girl Scout camping and astronomy program in August. It will be on Pine Mountain in Oregon, which is at 6300 feet elevation. Summertime night temperatures are supposed to be 30's and 40's. DD1 tends to be cold, so I bought a 20 degree bag at REI. But I am suddenly balking at the higher weight of this bag (3 pounds, 13 ounces for the women's long size that she needs. Becuase they are women's bags, they are a little warmer than a men's bag, so a 20 degree women's is like a 30 degree men's). This all means it's also a little more expensive, a little bulkier.... maybe just a little more than we need.
This morning I saw that there is an identical sleeping bag, same company rated at 35 degrees, and wondered if that would be better. (Nemo Viola 20 degrees vs Nemo Vioal 35 degrees).OUr family each has a basic, bulky, heavy Coleman sleeping bag rated at 40 or 50 degrees. That's worked until this fall, when our needs started changing.
That's because DD1, DD2 and I are all active Girl Scouts. Any of us would like to use this new bag on occasion for early spring or fall camping when our COleman bags don't cut it. One of us may do a backpacking overnight once or twice a year in the future, which is why weight is on my mind. DD1 and I did a primitive camping weekend in November and our current Coleman bags were very cold, just not adequate.
DD1 has other sleeping bag needs, but her COleman bag is probably ok. We camp as a family, but usually just in the summer when our existing bags are ok. She goes to a weeklong residential camp in Virginia in July and stays in cabin - existing bag is fine. One new thing this summer is DD1 will do a weeklong canoe trip in Virginia, but I don't think she needs a warm sleeping bag for that given the time of year.
So.... the warmer, heavier, slightly bigger 20 degree bag or the lighter 35 degree bag?
