Toasty & light - Arc'teryx Cerium SV Hoody - Men's

Lightweight, great fit... The fabric seems to be plenty tough enough - I would never expect a down puffy to be bulletproof and if it was a heavier fabric it wouldn't be in my pack. I have several different similar jackets from other manufacturers and design and construction of the SV is at the top of the pile.
The only con might be the zipper, as others have mentioned it is a non locking design. I suppose it has a benefit at times to be able to just tug on the jacket to unzip but it's something I'm not used to. If it's zipped up it stays zipped so if it's really cold you don't have to worry about it but if it's partially closed it can open further on its own. I'm not sure it's worth trade off or not yet... Thus the 4 stars.
