Marmots with fill of higher than 800 are assembled and filled in Costa Mesa California.
They're
assembled in China, but
"Filled and Finished in Santa Rosa, California." That means the last seam in each down channel is sewn shut after it's filled here in the US.
That's technically made in China.
I've become more relaxed about the whole China thing as it's impossible to overcome, but I still try to buy US made if possible.
Regardless, the 850+ fill Marmot bags are outstanding.
