Cool! I understand why oyu like that UQ. I have a Climashield "Yeti", before it was called Yeti but seems very close in construction except for CS instead of down and baffles, the original UQ made by WB. It has removable layers of CS, and just one of the 2.5 oz/sq.yd layers is remarkably efficient for at least 50F and I have even pushed it into the 40s one time, which is amazing IMO. Plus, just like with PL, less worry about moisture.
For I consider that the sufferings of this present time are not worthy to be compared with the glory that is to be revealed to us....that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God. For we know that the whole creation groans and suffers the pains of childbirth together until now.
