Just a thicker & heavier RidgeRest
Let's compare some numbers:
1. This pad is 540g vs. 400g for the standard RidgeRest. So it is over 35% heavier.
2. I also don't understand why they claim it's 10% warmer, since the R value increases from 2.6 to 3.5 (also 35% more).
3. This pad is 2cm thick, the standard RidgeRest is 1.5cm. Guess what? Also about 35% more. This basically explains the increase in weight and warmth. The aluminized coating probably doesn't do anything.
4. The only thing which is not 35% more is the price, $25 vs $40, a 60% increase.
