Adrian wrote a review of Marmot Troll Wall Jacket - Men's on December 24, 2011
Great fit, leaves plenty of room for layering...unlike some shells. The fabric is also a really heavy duty version of the Pro Shell, which is nice if your using this for skiing or climbing. I love how burly this jackets front zipper is, along with the flap that covers it.(really keeps the cold out) The neck is also nice and high so you can tuck your face up to your goggles...when your standing still in cold/windy conditions.
Its very similar in fit to the Exum....while it definitely is heavier duty in regards to the fabric, and also comes with a powder skirt which is essential for those deep days.
All in all I would say this is the best shell Marmot has to offer....and would have no problem saying it is on par with the best out there today. (Arteryx, Westcomb, and Peak Performance)
