For any considering buying a set… I am 5'9" and 160 lbs, 32" waist and 30" inseam, 47 jacket, and generally a medium fit on everything. I ordered a size small and it fits pretty well and I would order the same size again.
The size small, on my digital kitchen scale, weighs 9.2 oz's. The jacket weighs 5.5 oz's and the pants just shy of 4 oz's.
I ordered this set in the past week from gossamer gear.
