Therm-a-Rest Parsec 20F vs Yamatomichi UL Pad 100cm: which should you buy?
If saving weight is your priority, the Yamatomichi UL Pad 100cm wins — at 75 g it is 745 g (91%) lighter than the Therm-a-Rest Parsec 20F (820 g). That said, the heavier option may justify the extra grams with more capacity, durability or comfort, so weigh the trade-off against how you'll use it.
