I have a Bivy Chad and use it alone or with my Cave 2 as needed. Still, if it's going to be raining/snowing for a day or two I'd rather have somewhere to read a book or do a little cooking etc. We've been doing a winter trip every year since 2005 (08 was my last one). I would not hesitate to use this Luxe X-Rocket for a week in January. I have a sub 2 pound 15 degree down bag and throw that inside my Big Agnes Cross Mountain to shed the H2O. That combo works out great down to about Zero as long as I don't burn a hole in my pad! I'm done with inflatable pads. I've had two issues, both in single digit temps in January. Nightmare!
How about this kind of luxury?https://www.youtube.com/watch?v=_5962rzV6Ks
That looks like a good one for under 200 Duke! How bout them Giants?
