Any bivys that are just as lightweight a borah but more waterproof?

[rhendrix]

Looking at potentially upgrading my bivy sack, currently have a borah bivy, and while it serves it's purpose well in keeping me dry when there's condensation, I don't know how well it will perform in sustained rains like I had in 2014 hunting high country mulies. And that's a problem since I have a EE 0* quilt. So, anyone have any suggestions for an upgrade? The rest of my setup includes a mountainsmith mountain shelter lt, neo air xlite pad, and debating whether or not to add a sheet of tyvek, just worried that running a sheet of tyvek and a bivy sack is redundant.

Are you using the Borah Gear Snowyside bivy?That one is made from Event you should not have any moisture problem or rain getting you wet inside.

No just the standard bivy, thanks to you I just saw they make the snowyside eVent bivy and it's essentially what I'm looking for.

If what you are asking is whether anyone makes a reliable waterproof breathable fabric that is less then 1 oz/yd^2 then the answer is most certainly NO.
The only way you are going to get close to that is with a non-woven, like turning a frogg toggs poncho into a bivvy or something like the SOL escape bivvy.
otherwise you will just have to accept the weight and cost increase for an upgrade to Gore/eVent/whatever.

6 ounces isn't terrible. I can make up 6 ounces elsewhere honestly. Didn't know if there was a small company that made bivy a that I just didn't know about.

Honestly the snowyside bivy is just about everything I'm looking for. Just wish the face opening was configured differently.

I actually had one that I ordered with a center zip...actually an inverted T-zip like the Integral Designs bivies. I ordered it like that to use with my Slick bag, but then regrettably sold it to Bill Brown. I think he tried it with a quilt, but is now running it with a Slick...at least until he sells it back to me!

I have a couple of nights in a Sol. I am pretty happy

How'd you like it, was there plenty of room to move around, did you use it with a tarp or stand alone? I want the ability to either use my mountainsmith mountain shelter lt with the bivy, or if the weather is clear, just roll out the bivy and go to sleep. My only concern is if a rain storm rolls in the middle of the night. Guess I could always roll with a lighter tarp tent but I enjoy the mountain shelter lt a lot.

I didn't get a chance to sleep in it...just carpet test it in the family room. There is a lot of room in it compared to the ID bivy. I think it would be more than adequate for use with a tarp...that's what I intended to use it for. I don't know how good it would be for a stand-alone, but in an emergency, I'm sure it will be good. Bill has slept in it. Send him a PM and get his thoughts on it.

 

[rhendrix]

I'll send him a PM.

I have a Integral designs south Col II bivy made of event.It has arm holes and center zip i use it with my Feathered friends wrock wren bag which also has arm holes.I can cook ,sit out a storm sitting up without being in a burrito i take it everywhere.Add a tarp and nice functional light take everywhere set up.
That Borah gear bivy looks good

The snowy side Bivy is nice tons of room inside and so far havnt had a problem with condensation yeah the face vent part is kinda iffy but it has a loop on the top so you can tie it open.

 

[rhendrix]

I'm probably going to buy the snowyside bivy and pick up a supertarp or something similar. Just when I thought I had everything dialed in!

Mont-Bell breeze, Sleeping bag cover..6.3 oz. Its says that the Dry-tec is water proof and twice as breathable. I have not seen or used the breeze just read about on the internet, & have not stayed at a Holiday Inn.
Its smaller, I guess that where the difference between a cover and a Bivy is. But if you are going to use a tarp, would not a cover be enough. I dont see any kind of bug protection on it, not saying it does not have it, just that the web does not show it.

Good find! That is a pretty impressive weight for a WPB bivvy, of course they get there by omitting any zippers or openings so it is just a crawl-in tube like the British military bivvy sacks. I'd like to try one to see just how inconvenient it is, but I imagine most guys wouldn't put up with that.

 

[rhendrix]

I run a quilt, so I have to have my bag attached to the pad, if it weren't for that the mont bell breeze would get a serious look.

For what it's worth I just got my snowy side Friday but I'm pretty happy with it. I spent one night in it but that was in the back yard. I think I need a wider pad.

 

[MountainTracker]

What pad are you using? I've been looking at this bivy

Thermarest trail scout. I never thought it was narrow while using it in my tent.
