Why dont you just buy the non sleep system from solar??

I have solar SS and the non SS SP c tech beds - use the non ss during summer with an old cotswold aquarius throw and the sleep system thrrough the colder months

Also you could just unzip the ss from the bed you have now and use whatever bag / blanket you wanted?????

Covered in the first lline of my post, I prefer the way the fox bags zip onto the beds

The Fox R-Series system is very roomy in the bag.
