Nothing wrong with staring a new thread.
I have the Summer Jarbridge River. It is just like the regular Jarbridge River, but it is made with 3 oz Climashield rather than the standard 6 oz product. It weights in at 13.4 oz, and I have taken this quilt as is down to 41°, and with thin supplemental ⅛" pad, I have been comfortable at around 30°. This is my goto UQ for 8 months of the year, and I plan on using this anytime the forecast low is over 45°. It packs down plenty small (nerf football sized); I imagine the regular JR is a bit bulkier. FWIW, I am 6' 1", and the ⅞ length quilt suits me fine in the range I use this quilt.
Care is easy. Hook it up, use it, pack it up, <repeat as needed for additional nights>, take it home, hang it up to air out (a couple of days as needed), store loosely (I use a pillow case).
Let me know if you have any other questions.
