X-shorts are sadly no longer in production, but you can find them here and there, sometimes on e-bay.
I've had a mask fail at the beginning of a dive, and I've lost one in the surf on entry. The first time, I didn't have a spare, and had to can the dive. The second time, I pulled the backup mask out of my pocket and went diving. No question which outcome I preferred.
