A lot of boarding gear tends to be insulated. As above I much prefer to go with a base and a shell. Mid layer optional for when it's chilly, otherwise I overheat.
TK is brilliant for ski/ outdoor gear IF you're lucky with your timing. Over the years I've had some bargain technical gear including Peak Performance and Halti, but as long as you've got a wind and ideally waterproof shell anything will do. In fact I spotted a Halti (excellent finnish brand) 850 fill down jacket in TK today for the princely sum of £99. I will be ebaying my Rab!
I've got a couple of Norrona jackets but they're not really much better than the ME Changabang climbing jacket I ski'd in for a few years. You don't need a snow skirt in the jacket if you buy one that's a fairly snug fit (it will also keep you warmer), unless you're a powder hound.
