I am preparing to buy a 3 season sleeping bag and I think I have narrowed down my choices to 2 different bags. After doing some research I am looking at the Western Mountaineering Alpinlite or the Feathered Friends Swift UL. Both are 20 degree bags and the weight and cost are basically the same. The Feathered Friends bag is a little roomier by just a couple inches in the torso area and that might be nice for a big guy like myself. I was hoping some folks out there might have experience with these bags or other WM or FF bags and will please share that experience? Any help is appreciated as this is an expensive item!
