Does any one have a comparison of this bivy compared to the OR bivys ?

I always worry about condensation with bivys. I plan to use this with a tarp in summer or some kind of shelter in winter. Greg doesn't mention condensation issues...great! anyone else have experience?
I'm considering a 100% event bivy instead...
you shouldn't have condensation issues. maybe between you and the pad. thats the only place I get condensation

Is there any insulation on the back in this bivy? If not, is there enough room for a pad inside?
There is no insulation in there. It is a bivy only. You can indeed get a bag and a pad inside though.

I have a 25F sleeping bag can I use it with this and go camping in the snow and be fine on a cold night or this bivy only works to protect from rain but not from cold?
I personally have a 15F and I do just fine. It isn't designed to keep out the cold but the properties of the fabric do help in heat retention. The key to sleeping warm in the snow is a quality sleeping pad.
Simple and effective
I have spent over 50 nights in this bivy bag and loved it. But there are no bells or whistles, no hoop or anything over the face. You have to be someone who doesn't mind being uncomfortable. But the simplicity and minimalism of this set up is awesome. I did a twenty one day ski traverse and slept well every night in this baby, except for one crazy snowstorm night where I curled in with the boys.
Its super effective at what it does, weighs nothing but is not comfy when stuck in for 30 hours... no hoop is for the hardcores, since the fabric always falls into your face...
does the zipper go all the way down the...
does the zipper go all the way down the side? Double zipper for venting purposes?
I did some checking and the zipper for the Marmot Alpinist Bivy zippers to half way down, and it is a single zipper only.
None on mine.
Thanks, I ordered one last year and there was no mesh window. I returned it. It seems like you have to choose between mesh and "waterproof" unless you want a hoop. REI does a nice simple one like this that has mesh but you can't cover up the mesh! Nice if these things came in different lengths/women's models. Could save a lot of weight and get less tangled up in the extra material. This thing is huge.
