Bought the Slingshot vest about a month.5 ago and love it. I wanted the vest to be worn over layering items, so I bought a bigger fit (XL), and it fits well. I am 6'11", 180, slim to athletic build, and wear it over a number of items including the Patagonia Synchilla fleece. Warmth is ample, plenty of pocket space as it has both hand warming pockets that you can access from the side of the vest, but also pockets for stashing your goods in the two top access front pockets. Also has a stash pocket on the inside left. Very stowable, as it folds down into a small sac. Very light, I bring it canoeing with me in a dry sack for core temp. in case of the worst. The material seems to be solid, and can take just about anything. The vintage design is very cool. Great buy if you are looking for a warm vest, as the 650 fill down does the job.
