I'm still not getting it. This one and the Kelty Sine 20 bag have same rating. This one is synthetic, and the kelty one uses 800fps down. Yet they have almost the same weight. What am I missing?

YuanYuAre you just curious why they weight the same but are using different materials? That last part is the answer. Kelty is using a heavier fabric and more of it, plus extra weight in features, while MH is using a much lighter fabric with a pretty slim/tight cut and a minimalist design in these bags. The lower weight of all that combined offsets the higher weight of the synthetic insulation and the bulk is comparable. I think MH is a tad generous in their temperature ratings where Kelty has usually been closer to accurate, but I don't know about those new Sine bags (they don't look particularly lofty like a great 20F bag but that could just be the photos or a bag that wasn't allowed to fully loft before the session). The Hyperlamina bags have been one of the best choices for synthetics for awhile now. It's a nice insulation compared to most. The new stuff from Marmot this year is worth a look too.
