Its all the little details and quality that comes from a long standing specialized company. The only thing WM and FF make is down outdoor products and they are damn good at it. They know what works and what doesn't. Have you noticed that WM and FF don't announce new products every other month? Its because their gear is dialed and doesn't need a new version to replace the previous shittier version all the time.For those saying WM over SG and its not even close, I'm curious what specifics you are talking about? I have used both and now using a Feathered Friends. Besides made in USA the one thing I like WM or FF over SG is I like a full length zip, baffles that are horizontal (so I can move down around) and different lengths as SG comes in basically a long size.
