Big weather protection in a compact package.
- Single-wall bivy design saves weight by eliminating the need for a tent canopy, poles, and fly; ideal for three-season climbing and trekking applications
- Silnylon top panel repels wet weather and breathes well to reduce condensation
- DuraShield-coated floor provides advanced protection against wet surfaces
- Taped seams prevent water from sneaking in through the cracks
- Ultra-small, lightweight design won't weigh down your pack and packs up super small

Don't waste your money.

I used this bivy in Alaska and it was awful. The description says it breathes but it doesnt. This bivy holds onto condensation like crazy. I used it in a dry tent and woke up with my sleeping bag being really wet.

Picked this up w/ the idea that it would be a great piece of lightweight emergency equipment. Ended up having to use it in an alpine bivy scenario this year after encountering route finding issues and needing to bunker down for the night. Result was MASSIVE condensation on the inside of the bivy, even though the hood was never utlized. Thinking this was a fluke, I've since taken it out for some simple overnight climbing trips (where I wasn't too concerned w/ getting my bag/body wet) and have met the same result, MASSIVE condensation. For the price, this is unacceptable as you could get similar protection from a garbage bag or a foil bivy/blanket. Seriously disappointed in this and would suggest that anyone owning this pile test it out somewhere safe before being forced to use it in an emergency situation. You will be wet.

Nice dry desert trip and I wanted a bivy to add a little warmth to a lightweight sleep system and protect from dew, or spatters of light rain. It would do that, but so would a plastic bag. Soaking wet inside from condensation. (no, i did not breathe inside the bivy.) Temps dipping below freezing.
I tried a couple of nights and then returned it as soon as I got home.
EBivy nice summer gear
I bought about $1K worth of gear to do a 1200 mile self supported ultra light bike trip and the E-Bivy was about my favorite purchase. Rain in July in the western US was pretty non existent in 2012 but mosquitoes were a nightly occurrence. You can really hunker down in the E-Bivy leaving a little air hole between the top and bottom overlap material that keeps the little bastards out. The top layer does a nice job of keeping the dew off the sleeping bag. 90 degree days drys your gear off in about 15 minutes when you set up the following afternoon. This is a well considered summer piece of gear.
Good option to have
Super light, very small, and adds additional warmth. One night where my sleeping bag wasn't up to snuff I was fully in mummy mode inside this thing and it did see significant condensation on the inside, but this did not hinder the insulating properties of my sleeping bag. Unlike Rudi said I was able to get the bag back into it's stuff sack quite easily.
Very light and compact. Enough space. Pity that one cant fold it it back into it's original stuff/coke can:-o) sack. Need to cut off that section now. Space wasted, although it looks cool on the shelve for buying. The hood or cowl section is a little to short in my opinion. As I moved during the night the two ends continuously opened up, causing cold air and water to come in. Maybe Velcro or a waterproof zip could be installed to join the pieces together... The idea that the cowl or hood should come with riser bar or pole, because it lies flat on your skin and cause serious condensation. This might lift the prize, but would be more practical. I won't recommend this for a survival situation. The other model will be your better option.
does this bivy have a mesh no see um...
does this bivy have a mesh no see um component over the face/ head area?
Great to have in a pinch
This is a great item to have in a pinch. It provides reasonable protection against moisture, bugs, and adds a couple extra degrees of warmth. However, I wouldn't rely on this to handle seriously adverse weather conditions. It's no substitute for a tent or a gore-tex bivy. It is light, and packs down incredibly small, so it's a nice back up for pretty much any backcountry situation.
The Big Bivy:
Stay dry and no-see-um free with this Bivy.Keeps your sleeping bag clean and dry and are easy to get in and out of!
Good for size/weight
I replaced an OR Alpine Bivy with this due to its size and weight and I am quite happy with it. Obviously it isn't as impervious as the full on gore-tex bivy but my feeling is the trade off in weight (over a pound) is worth it if you are near or below the tree line. Even above it the adage light is right comes into play.
