I'm going to send a link to a picture of my altimeter and bivy as soon as I get my camera to dry out. It is waterproof camera, but I had it out in the snow/slush yesterday and it has some moisture in it. I've had this happen before, I just need to be patient and it will dry out.
To answer other questions: As far as usage goes, not a lot. I've only used the bivy once, so it looks like new. I don't remember exactly what I paid for it, but I know I got it on sale. Unfortunately, BPL doesn't sell it anymore, so I can't find too much about it. I'll try and get some pictures of it when my camera dries out.
The tent has a little more usage (three trips). There is a minor blemish on some of the netting. Basically, the threads are squished together where they should be evenly spaced. This means a bit more spacing on the other side, but not enough (in my opinion) to let in a mosquito. The blemish was caused by my being stupid, and squishing a mosquito using the netting.
I'll post an update as soon as I get the pictures up there. A couple people asked about the altimeter, so I'll go with the first PM I got (Dave) unless he doesn't want it. Thanks for your patience.
