Which YKK zipper does the Marmot Phase 20 use

[Elaikases]

Marmot only makes down bags with one side zip. I'm trying to find a bag to mate to a Phase 20 so my wife and I can zip bags together.

I've seen Feathered Friends uses the YKK #5. Does anyone know what the marmot phase 20 uses?

Thanks!

I'm trying to figure out which bags might be compatible.

I continue to do internet searches. https://backpackinglight.com/forums/topic/84734/ and https://www.reddit.com/r/Ultralight/...an&sh=ca8d2298 for example. This thread already pops up as I search.

I just had an asomely radical idea.
Call Marmot.
You’re welcome.
