I always see a tent described with a few different weights. Pack weight, fast pack weight, trail weight, and a few others. I honestly have no idea why a tent would weigh three different amounts. What's with this? And whose ever really had a ventalation problem either?
Another question I have, now that I'm thinking about it, is I have no idea how my trek poles attach to my bivy. I bought the middle of the road SD Navassa bivy and it doesn't make sense how I'm going to use my trek poles for it to stand up with. Getting in and out pull on it alot when I've got the top guyed out to a tree (just enough for some face room) so I can't figure out how to get it right. I've seen pictures with the poles in an X over the top but that really doesn't work.
And no I do not use my bivy with my tent.
