I have the exact same pad. I paired it with a BA Anvil Horn 0 bag and a thermolite liner. It was a solid combo down to 15-20. But a couple weeks ago it was 5 degrees with snow under the tent and it was inadequate. I was cold from underneath. Klymit hasn’t updated their R-value ratings under the new rating system. I think the pad is economical, comfortable, and moderately good for winter camping. Just some feedback, take it FWIW.Refresh.
I signed up for Klymit e-mail and several days latter I received a 30% off discount coupon for all insulated pads. Pulled the trigger on a Insulated Static V Lite. Free shipping also.
