This seems like a real breakthrough in cold weather wear. It can be hard to move in super bulky down or fiber filled jackets, and this seems like the answer for active cold weather wear.
Pros:

• Relatively thin.
• Ventillated armpits
• Waterproof
• Washable.
• Cost very reasonable, in line with high quality other jackets at $260. USD.

Cons:

• Not much that I can see.
• Only available in black at this time it appears.

If I lived in colder areas, or planned a really cold trip, I'd order today!
