Either Peapod or PolarPod. I have some questions for you who use these.

I plan on using it in +/- 15*F. I am short 5'5. I like to sleep on a diagonal. Will I be able to do this in a Peapod or should I just get the bigger PolarPod. Also, what is the weight of the PolarPod. There are no weight specs for this model on the TTTG website.

What else will I need beside a Pod to get this these temperatures?

Thanks,
