The minimalist, four-season Black Diamond Twilight Bivy is built from water-resistant and breathable NanoShield fabric that keeps weight to an absolute minimum and packs down incredibly small, making it ideal for an emergency shelter or as a sleeping bag cover. Built with a zippered entry across the shoulders, it’s easy to get into and use while sitting up.

  • Frameless construction to minimize weight
  • Proprietary NanoShield single-wall fabric
  • Year-round performance


Superlight Series tent canopies and bivys are constructed with NanoShield—Black Diamond’s proprietary breathable single-layer fabric. NanoShield is extremely water-resistant boasting the highest water column rating of any breathable, single-layer fabric. This is thanks to our exclusive Silicone Nanocell coating, which allows the fabric to remain light, soft and packable.

Twilight Bivy - Spring 2018 is rated 4.0 out of 5 by 3.
Rated 4 out of 5 by from for winter its not for rain. good summer alone use w no rain in your forecast. protects your bag from pine needles and what not. what you really use it for is snow. dry Utah snow is the best. use it w mega light or the older versions. dig down in the snow center pile for center pole. anchor the tent, stuff bags work great cuz you have them. dig the sides out a bit. and viola'! youve just made more space in your shelter than its stand alone foot print. its great to have your bag completey covered and no way is snow getting inside from your snow shelter. move around, dig around, melt your snow, sit on your bag and bed roll=cozy, no cold butt. and your bag is protected. bonus keeps frozen condensation off your bag. adds a tiny bit more warmth to your bags rating. igloos are perfect for it too.

Rated 3 out of 5 by from Very light weight, but not very effective The single layer fabric is effective at light rains, but any real rain and you are going to get wet. Honestly, I've found it so ineffective at keeping me dry that there are very few times I will use it stand-alone. I almost always use a tarp along with the bivy. If I know it's going to rain, I build a lean-to with the tarp and use it to shed off water while I sleep in the bivy under the tarp. I can see it as being useful in emergency and search and rescue situations due to it being so light and having some ability to protect from the elements, but for a reliable, stand-alone product, I say go for a thicker, more water resistant bivy. The extra weight is worth it.

Rated 5 out of 5 by from Light weight, compact! Good addition to my kit for Mountain Rescue operations. So small and compact I don't really notice in my pack!
