While tents protect campers from natural elements such as the sun, rain, the wind and also bugs, it also takes up the campers time to set everything up. A bivy is great for someone who is looking for a quick overnighter. While it takes little to no setup time, it can also offer protection like the tents.
As a product that comes from MSR, the AC Bivy is quite the popular bivy that people look at. However, there are not a lot of websites talking about this product.
- Ultralight for minimalists
- Durable floor so you can feel safe with it on rough floor
- Compact size
- Easy entry and exit
- Expect condensation
- Mesh rests on your face, bugs will be able to eat your face
- Not made for cold weather
- Ultralight Weight
- Nylon Fabric with DuraShield coated floor
- Envelope style hood allowing easy entry
Weighing only 1lbs, this bivy ensures it will be the last thing you complain after a long hike. However, to skim on the weight, a couple of things were traded off.
The body is made of ripstop nylon fabric. This material is waterproof, strong and breathable.
The space is relatively smaller as compared to other bivys. The envelope style hood does not have any zipper. This saves some weight, you can quickly slip into the bivy and close it up. However, this also allows strong wind to blow it open, letting some rain to leak inside.
Let’s look at individual components of the Bivy.

How Does It Compare To Others?
When setting up, the poles brings up the hoop, creating space between the head and the hoop. You won’t be having fabric rubbing against your face. This makes it more comfortable compared to the AC Bivy.
The hoop also has a zipper. This allows it to be completely closed when there is a need to. No cold air will be able to enter the bivy if it is completely closed. If you need to go to colder places, you should get this bivy instead.
Although it offers so much protection, it is quite bulky and heavier. The size is also smaller as compared to the AC Bivy. If you are not going for a long hiking expedition where weight is going to be an important factor, you can consider this bivy.
There are not many feedbacks on this product but I would say it is similar to the AC Bivy. It is a frameless system so there are no poles to set up. Because there are no poles to put the hoop up, you will still face the same problem of having the fabric touching your face.
A user mentioned that it is not waterproof so you might want to consider other choices if you heading to wet weather places.
This is an even lighter bivy sack. If you are looking to shed even more weight in your backpack. This can probably be one bivy to consider.
The Slumberjack Contour Bivy also comes with additional features like multiple zippers and arm openings. This bivy provides even easier access than the AC Bivy as you can zip from the top or from the bottom. If you want to cook your meal or just move your hands around, you use the arm openings while still being protected from the rain or bugs.
If you are okay with a little more weight in your backpack, you can consider this bivy as it offers more useful functionalities and comfort.
Should you buy?
In my opinion, I will rather go for the Slumberjack Contour Bivy because I think that the extra functionalities and comfort is worth the extra weight.
If you are someone who is going to save as much ounce as possible, you can consider this or the Black Diamond Twilight Bivy. But, do expect there will be some rain entering the bivy or the discomfort of fabric on the face.
