My wife and I are planning a 10-day trip to Olympic National Park for next summer. I've been there a number of times, and have quite a bit of backpacking experience over the past 35 years. She has been with me and our son on a few backpacking trips, but nothing this long and nothing with just the two of us. (We've occasionally car camped together.) I'm looking to minimize weight and maximize comfort, both hers and mine.

She's little... 5' 2" and 115 pounds or so. I'm 6' 1" and 190ish.

We could certainly do the usual sleeping bag and mattress combination, for each of us, but I'm wondering if there's a double mattress option with a double bag or possibly a quilt that would work well.

I'm also looking for a reasonably lightweight, preferably freestanding, tent with adequate floor space and room to sit upright. We have a Big Agnes Fly Creek, which works but is a little cramped. (I've used it by myself quite a bit and it's fine... with her, there ain't much room to spare!)

All suggestions/advice appreciated!
