Last Friday, I bought this 3 in 1 jacket for a weekend at Northstar. It's my second ski-specific clothing purchase in 30+ years to go with my North Face Freedom non-insulated ski pants.
You can look up the tech specifics and pricing here:
Suffice it to say, the jacket is warm. Perfect for last Saturday's windy snow showers and low 20s temps. I only needed a mock zip turtleneck underneath. The mid layer is a 550 fill down jacket that zips into the hardshell. I wore them apart so I could zip up the inner jacket all the way, and open the hardshell or pit zips as needed for ventilation. Sunday was a bluebird day. I only got warm twice, once while standing in the largest lift lines of the year, and while tree skiing. Even though I worked up a sweat, both jackets wicked and breathed enough after I got out of the trees. I didn't need the down liner for Sunday, but I needed to find out my temperature limits. Easy enough to cool down though by unzipping.
The Freedom non-insulated hardshell pants are great. They're fully lined and warm enough on their own for all but skiing in the low teens.
Keep the down jacket in the car for bluebird tree skiing and especially for White Rabbit runs as seen in my photo.
SportsBasement is slim pickings as all the ski clothing's been on sale for months. I got lucky. I was looking for a warmer layer under my soft-shell, but the 3 in 1 jacket was just a few dollars more and couldn't pass it up.
They are so choice. If you have the means, I highly recommend picking them up.
