So reading about Patagonia today. They are apparently famous for donating 1% of their revenues to environmental causes.
Now Patagonia makes some nice stuff. But so does North Face, Marmot, and for that matter REI and LL Bean. You pay a 5-20% premium to get the environmentally-conscious Patagonia brand name compared to comparable products from their competitors.
So, say, Patagonia only collects a 5% premium and donates 1% to charity, that's a 4:1 profit bonus. That's at a minimum. Gotta be millions of dollars a year they make off their well-meaning customers.
If you really want environmentally friendly gear, you would do much better to buy TNF or Outdoor Research or whatever and cut a check for 5% of the price to your favorite charity.
