Full face masks for cold water diving

[ScubaDo]

I plan to do my first ice dive this January.  The coldest water I've been in was 38 degrees.  My friend just got two masks with com units.  We plan to try them in a pool soon, but my friend gets cold very easily even in a dry suit and thinks I'm nuts for wanting to ice dive.  I hope to borrow a mask for the ice dive, but would like to get my own.  I have yet to try a drysuit myself, to me, drysuits isn't diving unless you're wet.
