Western Mountaineering

Western Mountaineering has been hand-sewing sleeping bags in the same San Jose, California factory for more than fifty years, which makes them either delightfully old-school or the last people on earth still doing this properly, depending on who you ask. Two mountaineers started the company because they wanted a better bag than anything on the market, and the habit stuck: every bag is still cut, filled, and finished by hand by people who've often been doing exactly that job for decades. They'll also be the first to tell you that fill-power numbers on a lab report are more marketing than physics — loft, down density, and construction matter more than the big number on the swing tag, and they build accordingly.

That shows up in the baffle work. Continuous and box-wall baffles keep down from sliding into a useless pile on one side of the bag at 2am, and a differential cut gives the inner shell room to loft without squeezing the insulation thin at the seams. The down itself is responsibly sourced and traceable, never from live-plucked or force-fed birds, because a warm night's sleep shouldn't come with an asterisk. Simply put: these are bags built to be repaired, not replaced.
