Bivies and Rain

[TwoRoads]

I'm wondering how bivies compare with tents in the rain. I have a Double Rainbow Tarptent, which I love, but might like to try a bivy to get a smaller footprint. I'm thinking this would allow me more flexibility in deciding on places to camp for the night. I've looked at the Outdoor Research Alpine Bivy, which is made of GoreTex, but I have a GoreTex jacket which has kept me very dry over the years, but allowed me to get soaked in one very hard persistent rain. Why wouldn't a bivy do the same thing? And of course, that's out of the question for me, since I use a down sleeping bag. Feedback appreciated.

I used a similar bivy off & on for a year or so (tis was maybe 15-20 years ago). Really bad rain in damp weather and I got serious condensation. Getting in and out was wetting. Not being able to sit up and do minimal moving around was hard to dal with. Lack of gear storage was inconvenient. It was a phase I was glad to move on from.

You are correct that flexibility in picking a sleep spot was a big plus. I could literally drape around a tree trunk on a steep slope, or slip into brush with no height at all. Even thinking about it right now I find myself thinking that's great! But in practice it was rarely helpful; you still need room to get in and out and maneuver around.

It just wasn't worth the disadvantages.

I only rely on a bivy when I know I'm gonna have good weather, but expect lots of bugs. If rain is expected, I'm putting up a tarp for the extra space and comfort. My bivy doesn't even come on 90% of my trips anymore. With smart pitching, my 9x7.5' tarp is plenty large enough for me to avoid the blowing rain that might come in the side, or I'll stick my feet into my trash compactor bag pack liner to keep them dry.

I believe you can accomplish 90% of your "throw down in small space" without the negatives of a true bivy with a non waterproof bivy and small footprint tarp such as an MLD solomid. Good weather, no tarp. Bad weather, set it up. A mid style tarp is a very small footprint, I made two that are actually a scaled down version of a solomid. I have set them up in some very tight spaces. IMG_0453.JPG

If you want to try a bivy for not much $ to see if you like it, you can look on YouTube ans see how to make one out of tyvek and some double sided carpet tape. I've done a lot of residential construction so I have extra rolls of tyvek around (they come in 9' widths) but I'll bet you could score a 6x9' piece from any construction site to try it.

The only way to get in and out of a bivy and not get wet when it's raining is to have a tarp over it, which kind of defeats its purpose. However, if you can manage to get into it before it starts to rain and out of it after it stops, then your all set. Since it often just rains or drizzles overnight, getting in and out when it isn't raining isn't too big a problem.

Since you can't bring anything else into the bivy with you to keep dry, you need a waterproof sack to put your clothes in, which I then put into the pack. I cover my boots with my rain jacket next to me.

I have an OR Advanced bivy and mostly use it for short trips in the fall when I'm pretty sure it's not going to rain. I can use it on tent platforms here in the Whites easier then a tent and it adds a few degrees to my sleeping bag. The bivy actually weights a little more then my SMD Trekker tent.

Here's a picture of it covered with frost from an overnight trip a couple of days ago when the temps dipped into the 20's.

I have been using a bivy for several years, but recently decided to switch back to a tent. The biggest problem isn't rain bleeding through the bivy, but the condensation that doesn't escape. Any time I zip the bivy up to keep the elements out, I end up keeping the condensation in.

I bought a REI Quarter Doom tent that is essentially the same weight as my bivy or my hammock.

In "very hard persistent rain"/long duration/very rainy weather wanting a smaller foot print you can do better from a performance and livability POV than just sheltering in a OR Alpine Bivy made possibly a more important priority on longer duration trips. Start adding other considerations into the mix(wt, $, comfortability/livability, longer backpacking trips, greater kit sizes, consideration of a wider spectrum of bivy types/consideration of a non stand alone bivy as you are) things can be reconsidered. For example, there's not much difference in footprint size needed between a MSR Hubba 1 p compared to the OR Alpine Bivy.

Again, bivies come in different versions, different designs, and aimed for different uses. Some are stand alone and some are not. So, respectfully IMO, "I'm wondering how bivies compare with tents in the rain" is a loaded parochial question.

Nice to have the flexibility as Malto said with the bivy/tarp combo or knowing how to set up a tarp in different configurations depending on things like available campsite space as Maui Rhino said. I'll also echo some of what Will said although I found the OR Alpine Bivy was acceptable as I once used it for a few yrs awhile back on wk or less duration alpining - lower tier mountaineering and alpine/sub alpine climbing trips which is what this bivy IMO was primarily designed. When sleeping on narrow rock ledges, smaller footprints sometimes associated with these terrains, etc I found this bivy OK on shorter duration ridge line somewhat exposed locations where a risk of some snowfall, cold, and freezing rain could be encountered. For persistent rain on backpacking trips of some extended duration I'll pass on the OR Alpine Bivy.

I'm a regular tarp(different types, including shaped mids) and bivy(different types) shelter person for backpacking but I let the terrain and anticipated conditions and my trip dictate the shelter.

What one might consider in their choice of shelter including choice of bivy is it impacting sleep system choices/components and character.

If much rain isn't expected footprint size and kit complexity required doesn't get any smaller or easier than cowboy camping.

Get a used military one on amazon for cheap. I have stayed dry in some serious monsoon rains in one.

Thanks, everyone for sharing our experience. My goal, and what gave rise to my question, is that I'm trying to build flexibility into my end of the day routine to allow me as much hiking time as possible. I'm not all that crazy about night hiking, as I'm often hiking in places where there are severe dropoffs close to the trail. I do have a good headlamp if need be though. I've found that I can save a little time in my end of the day routine by cooking earlier in the day if I find a suitable spot, thus removing that from the night time routine. Ironically, finding a suitable bear bag limb in the middle of the woods isn't all that easy and is therefore time consuming. So I'm considering an Ursack to add flexibility without worrying too much about losing my food. Based on your comments though, I'm pretty sure I will be staying with my Tarptent Double Rainbow for a shelter, since the disadvantages of a bivy seems to outweigh the advantages for most of you, and some of your comments sort of confirm my concerns about possibly getting my down bag wet. I did love the suggestions about the REI Quarter Dome and the MSR Hubba. I might consider changing my tent choice to one of these for ease of setup (and again time) afforded by the snap hooks rather than the Tarptent sleeve, but probably not a priority if I do consider that.

I agree, the worst is the condensation, right behind it when the temps climb above 70° and it becomes an oven bag. Yes it is going to get wet - it will be more uncomfortable.. this is what UL is about. When it comes to oven bag.. its all about mosquitos. They come in clouds as you attempt to sleep. It requires a thick skin and not being a claustrophobic person. the clear trade off - no back problems.

Here's where the WB folks can help you. They can suggest ways to increase hiking time and lessening night time routine chores. You might consider starting another thread concerning these topics because the folks here will have a plethora of suggestions. I'll start the ball rolling.

1) cowboy camp when conditions allow
2) go no cook for food, WBer Garlic has been doing it for yrs
3) go UL which can usually mean having less stuff to account for unpacking and packing back up
a. organize stuff especially small stuff into one larger sack, have a sack for personal hygiene products, another for electronics, possibly another for your emergency medical kit, etc
4) have a system to the way you pack your backpack, it aids in not losing stuff and organizing as you unpack
5) anticipate the day's hiking conditions
a. if rain is expected store that rain wear in an easily accessible place, likewise store your shelter near the top of your pack possibly even storing it on the outside of your pack for quick access as you find your campsite
1. practice setting up your shelter and unpacking your backpack in the rain in your backyard attempting to keep what needs to be dry dry. think about how you handle this situation....when on trail in a remote area What's the order of priorities in different scenarios in foul weather as you unpack
b. have a general idea of where the day will end having several possible locations in mind already anticipating from looking at your topo maps or GPS/electronic topos the on ground situation. this might also help to you to understand what varieties and character of various trees will likely be available or whether you'll even be above treelike

No tree hunting required with a bear canister. I also like to hike into the evening and decided it was worth the weight to save the hassle. I have never lost a crumb of food to an animal. I use a tarptent (Z-packs Solplex) and have pitched it in some pretty small spots, by using longer tie outs with mini line locks. It works more like a tarp that way. It weighs no more than a bivy.

"I might consider changing my tent choice to one of these for ease of setup (and again time) afforded by the snap hooks rather than the Tarptent sleeve,"
I don't know how you do it but inserting the pole into a sleeve can be done pretty fast and easy if you lift the sleeve entry point up and insert the pole downwards and then keep pushing it in.
<span style="color: rgb(51, 51, 51); background-color: rgb(235, 235, 235);">
you can see that it can be done in about 30 sec. Not super fast but it is still only 30 sec.

One day we'll be able to throw a Chapstick or bubble gum sized package onto the ground and with an app and telekinetic impulse it will pop out into a fully erected 2 p tent.

Great responses and suggestions since my last post. They are all helpful and I appreciate the input. Although I haven't made any hard fast decisions, I am leaning toward a Bear Vault 500 instead of an Ursack, and thanks to Sandy for her suggestions. I originally had gotten the idea of the Ursack from a fellow hiker who had one and it seemed like something that would give me more flexibility by not necessarily having to hang it. Then I got to thinking that even if a bear could not get the food, I just might end up with a sack of flour after a bear gets done chewing on it. So I'm thinking that perhaps the sacrifice of weight for the canister might be worth it (My pack is down to 30# including food and water for a five-day rip) for the convenience of just being able to lay it on the ground some distance away. I do agree with Franco too, as after some practice, I pretty much do thread the pole much the same way as the video, and as I said, I do love my Tarptent, which has served me well. Still, I slightly do prefer the clip system, so that option remains open. Wise Old Owl's comments about the oven bag (re: condensation), along with some from before my last post have pretty much pursuaded me to abandon the idea of a bivy. Loved Dogwood's list of suggestions, and so I will be posting in other threads for other ideas. And, Dogwood, let me know when that app comes out. I'm in.

What a deal!!

You may also want to look at the bear vault 450, I can still get 5 to 6 days easy in it and the size is just right to fit in the bottom of my pack. Your food volume may vary, I am a small person. I can also get 9 days in a Bearicade Weekender, but the metal on it rubs the inside of my Cuben pack so for 2 oz. more and slightly less volume I carry the BV450 when using the Cuben pack.
