My wife and I just bought one of these quilts as a 5 year anniversary gift to ourselves and used it on a 16 day, 200 mile road-to-road traverse of the Talkeetna Mountains in Alaska. Evening temps were mainly in the 40's, though it did drop to the upper 30's one night; it rained 15 of the 16 days and regardless we were sometimes damp/wet from packrafting. We like to camp on ridgelines to keep mosquitoes at bay, so there was almost always a breeze, and we were squeezed into a Big Agnes Fly Creek 2 tent. We slept on one full length ridgerest (my wife's side) and one 1/2 length ridgerest supplimented by pack, clothes, etc (my side). I typically would have brought a one pound down sleeping bag, slept in all my clothes, and on some nights would have probably been a little chilly in the wee hours; my wife would have brought a 2 pound down bag and still been cooler than preferred. With the JRB quilt, we were toasty warm--warmer through the night than we've been on a trip in quite a while--without needing to wear all that much (which was nice in a shared sleeping system)... I'm sure the quilt would have been fine down to below 30, and as shoulder season fast approaches we'll test that theory.
One useful feature that I wasn't aware of before sleeping under the quilt is a center line marked on top; this helped us police any hogging of too much quilt. The quilt gave us more than ample coverage, and within a day or two we had sorted out how to tuck the quilt here and there to stop all drafts. It also allowed much more tossing and turning than one can easily do in a traditional sleeping bag, which provided a better nights sleep.
We got the additional wings (sewn on), sewn in footbox, and 2 ounces of overstuff (did I mention that my wife typically sleeps COLD?), and it still came it at less than 2 lbs. It's a bit long (we're a bit short), so we're going to get one baffle section cut off. I love the concept so much that I've already ordered the 1 person version of this quilt for the rare solo trip, though the shared body heat will be sorely missed.
We had looked at Nunatak's tandem quilt, but the price and 8 week lag time sufficiently deterred us. I'm sure the Nunatak quilt would have been wonderful, too, but given that the Jack's R Better quilt was cheaper and faster, the quality is great, and the customer service was superb (seriously, I talked to "Peter Pan" for more than an hour one weekend morning about sleep systems, trips, etc, then for another half hour later that night, and he was incredibly helpful and personable... he was the one who called me after I sent him an email), I'm really glad we chose to go with the Mt. Rogers. If you're thinking about getting one, stop thinking and order it! You might just find yourself hiking faster so you can camp earlier and get in more warm-quilt-goodness.
