Brandon brought several of these Winter Lynx UQ's to the CO Winter Hang last weekend, and let some people borrow them to use - including MrsMustardman. The next morning, we bought it from him.
The ridgerunner/lynx combination is, in my opinion, the most perfectly designed, no-hassle hammock insulation system ever devised. It uses just enough down and fabric to cover all the parts of your body that need to be warm, it fits with no adjustments or fiddling necessary, and it is dang toasty.
Some people might say the thing that really sells the Ridgerunner is the comfort, or the view, or the absurd spaciousness of the bug netting, but I actually think one of the greatest selling points is how perfectly this quilt fits, allowing you to spend less time and hassle setting up your insulation, and more time cocooned in down.
