Marsupial size for Vortex UHD 12x50

[BleedingCoffee]

I’m looking to get a Marsupial enclosed bino harness for my Vortex UHD 12x50 binos. The Marsupial sizing guide recommends either a medium (with breaking period) or a large enclosed model size.

Anyone have this setup? What would you recommend getting for a size? Medium or large?

I would follow the Marsupial Sizing Guide.

I carry the Razor HD 12X50s in a medium and it fits great.
