One caution, the tubing is burst proof, BUT and fittings are NOT.

Though often when a PEX system freezes, the freezing water in the fittings will expand out into the tubing instead of bursting the fittings... That is not to say they can never burst, but we had a good hard freeze of our home during the Texas blackout... And no pipe damage at all.. (Thank goodness) And our house even has 2 hot water heaters in the attic and all the associated piping exposed to un-insulated space...
Love Pex...
FWIW, I even plumbed the air in my shop using PEX and sharkbite fittings about 12 years ago. Not a single problem or leak in that time. And pex splits when it bursts... No shrapnel like PVC would...
If you're going to work with it much, it's handy to pick up a tubing cutter like this:

Works great on vacuum and radiator hose as well. Nice clean, square cuts...

We were staying at our cottage one winter and had a heating system failure when we were away overnight and froze it hard, it was -15C inside when we got back.
The only leaks we had once everything thawed out was the 2 feet of copper in the shower running to the showerhead and the kitchen sink spout split as well. All the distribution lines are PEX with mostly crimped fittings and a few compression fittings. It's great stuff, the cold water line under the sink would freeze every time it got really cold and the wind was the right way, never a leak.
