Hmm... Rummaging around, what can I find?
Three MSR stoves
A Western Mountaineering down bag
A Feathered Friends down bag
A Feathered Friends down jacket
Two Never Summer snowboards
A pair of 40 Below overboots
Two BearVaults
A Thermarest sleeping pad
A Ridgerest sleeping pad
A pair of MSR snowshoes
A pair of Black Diamond crampons
A whole bunch of USGS and Trails Illustrated maps
A Katadyn water filter
A dozen or so Nalgene water bottles
Most of my favorite stuff is made in the USA. You're right about clothing for sure though. Patagomia does actually have a few small items that are made here ("mens boxer briefs", for example), but it seems like things that involve sewing tend to be from far away. Tents and backpacks too.
Someone in another thread hear, or somewhere, suggested going to the REI website and searching on "made in the USA". There is more stuff than I had expected.
Cool idea, I hope there'll be a lot more posts here.
