Outdoor Research is a company that makes camping stuff. I presume they wear lab coats when they hike. They've evidently gathered the right facts, because my bivy has been great thus far.
In 2007, I bought an expensive Gore-Tex bag in Montreal. I used it to sleep in some pretty weird places. Now the white coating on the floor is flaking off and getting white shit everywhere. And whatever seals the seams is turning yellow and falling apart. Fortunately there is an "infinite guarantee," so I investigated that.
I put that bag through its paces, and I understand that things wear out. Regardless, once I sent some photos, they said they'd help me out. If I send them back my bivy, they'll send me a brand new one. The problem is that it takes a long time. Fair is fair, but I'm going to be on the trail in a week.
I don't know. Either I'm going to send back the bivy, and hike around with a whole tent, or I'm going to delay the bivy return and wake up covered in flakes of white shit. Probably soon would be a good time to decide. There's this question and several more.
