A perfect ultralight bivy that weighs just over one pound.

For the Lightsabre Bivy, Black Diamond took the burly Bibler Tripod Bivy's design and put it together with the lightest, most packable materials they could find. The Epic fabric that makes up the Lightsabre's body is highly water resistant, good in everything but a flat-out downpour, and breathable so you don't have to contend with drippy condensation inside. A mesh window above your head eliminates the dreaded bivy claustrophobia attack without exposing your skin to ravenous insects. DAC featherlite poles and a silnylon floor strike a balance between weight savings and the strength necessities of a reliable shelter. If you're shaving ounces from everything in your pack, or space is a concern (IE: two saddle bags to live out of) the Lightsabre Bivy is the fair weather solution. For rough, wet, or extreme conditions check out its big brother, the Bibler Tripod Bivy.

Unlike other posters, I had no problems setting up the bivy, however the poles are exceptionally tight during initial setup. The construction appears to be quality however:

At 6'2" there is no way I will fit in the bivy with a sleeping bag. Even if everything would fit, entry/egress with a sleeping bag and the zip of the bivy might prove very difficult. This thing is going back for the simple reason that it is not big enough.

setting up the light sabre bivy for the first time. had no problem with the two head poles but the foot pole was harder than hell to install. Any tips or idea what I'm doing wrong?

Responded on

That's definitely the toughest pole. You have to pretty much try to bend it in half with a hand on each end and just shove it up in there. At least that's what I do. It is by far the tightest fitting pole of the 3.

Does this bivy retain any of your body heat? My concern is if i got a 15 degree bag and it adds like 10-15 degrees of extra heat. That would work out to the equivalent of a 0 degree bag. Any know?

Responded on

I camped out in this bivy with a 30 Degree back (Sierra Designs Nitro) and the temp got down to 23. I was a little cool in the morning but still alright. I would say that this MIGHT add 5-10 degrees. Depends if you're a warm sleeper or not as well.

Could a medium sized pack fit in the head area comfortably?

Responded on

Not really if you want room to put your head. I say that somewhat facetiously. I'm 6' and definitely don't have room to put a pack in the head area while still maintaining room for myself. If you're a shorter guy, say 5'8" or less, you might have room to sneak a 20-30L pack in there.

Check the picture I added last month, "fun in the snow" that should give you an idea of the actual size of the head area, in comparison to the length of my torso. Also, the plastic bag in front of the bivy are my trail runners - size 10. I probably could have stashed them in the bivy, but there really wasn't all that extra much room.

For summer trail runs I have a 25L bag I pack, bivy, pad, sleeping bag, water and a little food. I can fit in in there with me, but it's basically empty at that point.

That's a lot, more then I intended on writing, hope it helps.

I'm wondering what they mean when they say that the EPIC fabric is "highly water resistant"? That makes me a little nervous. Is this a tent that can withstand the elements and a rain storm or not?

Best Answer Responded on

Oh, this can take whatever nature throws at it. EPIC fabric is deemed "highly water resistant" because water *can* get through the fabric when it is subject to extreme pressures. What this means to you is that a windblown downpour won't even phase the fabric, but a high-pressure fire hose has a slim chance of forcing some water through.

Review Title

Used this for 30 days on a bike trip through Baja, Mexico. Condensation inside the bivy caused me to wake up soaked every morning. Even with the fly completely open and then the mesh completely open, still woke up wet. Eventually slept out and used it as a ground sheet. Thought at first it was the nature of bivy's until i met up with a friend with a different bivy who didn't have this problem. Can't get much drier than a Mexican desert so can't see where this bivy would be useful - sent it back.

Keep it vented

For traveling ultralight and compact this is a great unit. I didn't like the seam sealing process and wish they would have sent a thinner silicone or advised me to warm the silicone up a bit to make it flow easier. I found that it's best to not zip it up too tightly and make sure the vent at the feet doesn't get blocked, there is a small air space that is coming in contact with your sleeping bag and it can easily get very damp. I ended up with opposing zippers, sleeping bag on the left and bivy on the right, but it seems to work just fine with this bivy.

Pray for low humidity

Otherwise, you're going to be soaked in this thing.Condensation is terrible. Last weekend it rained all night, one night in the Eastern Sierra. Fortunately it was the last night of the trip.I might carry it again on any overnighter where I don't have to worry about drying out my sleeping bag. It's wretched to get into and out of. The zipper only goes partway down. Make sure you have a right side zipper on your bag. Don't buy a footprint. I use cheap plastic tablecloths that will last a week and only weigh a couple of ounces and cost a couple of bucks.I think I'll spend a bit more time on the Bowflex so I can haul a few more pounds of tent.

Is that a loaf of bread in your backpack?

This is a great bivy for fast and light treks. I've used it for long trail runs where I plan on staying out overnight, and for regular backpacking trips. It packs down smaller than half a loaf of bread, and presumably weighs less too. The 3 pole setup (2 hoops, 1 spine) is easier after setting it up once or twice, but not difficult to begin with. It's great to be able to lay in there and look out at the stars through the mesh screen - find another bivy that can do that...

The reason it gets 4 stars - if it unzipped another 6" it would make getting in and out of the lightsabre way easier. Are you listening BD? Yeah, it might add half an ounce, but for anyone over 5'5" it'll make getting in and out of this bivy worlds easier. Seam sealing it after I got it wasn't exactly the most fun I've ever had either.

Responded on

Another note after having camped with this bivy in the 20's (degF) - it doesn't vent the best (when zipped up 90%), and there was a considerable amount of condensation frozen to the inside. This shouldn't come as much of a surprise (it is a bivy after all), but I just wanted to point it out and add it to my review.

I've also gotten a bit better at manipulating myself to get in and out of this bivy, although it would still be easier if it unzipped a little farther.

Lastly if you have the option to get a sleeping bag that's right zip (vs left zip) it will make your life easier, since it will line up with the zipper on this bivy.

This is a bivy (and a pretty good one at that)

I've used this bivy for 100+ nights (sometimes with a beta-light if it's really pouring rain), and it's pretty good. But it is a bivy. That means that it's tight (but way, way roomier than most bivy sacks), has condensation issues (just like most bivys since they rest right on your sleeping bag, inhibiting airflow), and isn't a tent (but that's why you buy these things, right?!)

Pluses -- the lightest, most compressable, roomiest bivy that I have seen. Minuses -- must be very carefully seam-sealed to be water-tight, not super-breathable, not super-weathertight.

Black Diamond sells a "Ground Cloth" for $25 for use with their bivy sacks. You sleep on the ground or a matress and inside a sleeping bag.

Very decent bivy

I have been using this bivy for over 2 years and it is a fine piece of equipment. It is easy to set up, doesn't need to be staked out (though it can be), and is a fair price. Though there is certainly some condensation problems and a little leakage, it holds up well for something so light and small. It is a little hard to get into and out of (I am 6.0') and hard to move around in. Overall a great product!

Responded on

Sweet, that is exactly what I got it for this year, JMT in early July - All ya'll who want a super comfy bivy with no condensation and perfect entry and exit position and all that just need to get real. This is backpacking. It is light, it will keep you pretty dry and you will sleep soundly. Just enjoy the trails and be happy your not carrying a 4 lb tent.

Good Fast & Light

it's light at just 1 lb 10 oz. just for that fact alone you give up some other comforts. i bought this to do long multi day adventures where i don't stop. the bivy is for weather that rolls in and stops me. so i have somewhere to hide rather than just a space blanket. it's light and does exactly what i bought it to do. however it is a bit tricky to get into, and i have to admit stupidity here - if you haven't set it up in a while it's not easy to figure out. me and phd took over an hour and had to come back to it on a hike through the enchantments (yes we had the instructions!). and of course there are compacted condensation issues with a smaller overall space inside. i think that is bottom line: it's perfect for adventures where you will need a bivy but don't wanna travel with the extra weight. but it's not easy to setup.

pretty nice bivy

This is the first bivy I've owned and I sure am glad that I bought it. We encountered hail, rain, and snow all in the first night I used it. It held up great and seems to be pretty water resistant. It does get some condensation but it wasn't a big deal. Overall. . . it's great for the price. I didn't want to spend $300 for a fully waterproof one so I think this is the best for the price. I'm 6'2" and I could get in and out. I saw others complaining about it and it's not really that bad. I wouldn't want to have to get in and out of it all day long but once or twice a night isn't so bad.
