Myke Dronez wrote a review of Marmot Guides Down Sweater - Men's on April 8, 2008
I previously owned a Patagonia down sweater- when the zipper broke I returned it for this which is much beefier in size, warmth, and materials. Great for chilly belays when the other wasn't quite as warm. I also love the heavy duty double zipper because you can leave the bottom open so your belay device doesn't make the jacket ride up- very very cool for climbers. If you need something to move around in this might not be it but for powerful insulation that will keep you warm while standing still, this is the ticket.
