First Ascent, the Eddie Bauer mountaineering company, makes world class stuff and is having a kick assed sale right now. Their microtherm down shirt is super light but warm for rock climbing or backcountry skiing as a layer, and is on sale for only $99. 800 fill Euro down. Great price. For downhill skiing you can go heavier and get a better shell.
When I was your son's age decades back I asked my parents for a North Face jacket it was what all the cool kids in the ski movies were wearing.
On Christmas I opened a box with.. a North Face jacket. But under it was a Helly Hansen jacket. They said the guy at the shop said it was better. I tried them both for about 1/2 day each and agreed. The Helly Hansen was better, more comfortable, more features, lighter, softer. I returned the North Face one.
So that's an option, check the return policies, buy him a couple/few and let him pick his favorite.
After that Helly, my next was another Helly, now I'm on a Marmot. Often getting a good deal is a major factor. I don't think I've paid over $150 for a jacket.
It gets worse, Kerwin. Hanna became a teenager this month and is rocking mascara and an iPad, taking guitar lessons, wants a Fender Strat, and after skiing since she could walk is transitioning into snowboards. wtf? Can we go back to '85 so I can spill champagne on your floor then we'll barnstorm Neuvo on NYD with crushing hangovers?
