How many grams of insulation in the Thermal R liner?

(Also I noticed that your waterproof ratings are wrong, as far as I can tell, for many of the Marmot products. They have MemBrain & MemBrain 10. MemBrain 10 is only 10,000/10,000 & 25 PSI. You have a few MemBrain 10 products, but you're showing the specs of MemBrain)
