Mark, great job on a superb product.
Ditto this. Field-tested yesterday about 22F in the morning, I layered a base (under armour cold gear) and a thermal which is what I would normally put on under a hoodie. After an hour I ditched the mid layer and probably would've been safe with just like a long-sleeve t-shirt underneath. Wind wasn't a major factor but from wearing this around town in some gale force (50mph) winds I can say it's definitely good in the windproof department. On the slopes it's ridiculously warm.
I'll have a full/thorough review posted after the new year for those who might still be on the fence, but the HPH is legit in my opinion.
