What is a Bivy Sack?

The name may appear strange, yet the real name of a Bivouac is even more bizarre. In function, these are merely a personal shelter that is sufficient for one person.

They appear very similar to a sleeping bag from the outside, yet these deliver more room for you to move around, and some come with a mesh window so you can see out.


However, with the introduction of newer breathable materials, these can now come with no window and can be fully zipped closed from the inside.

Initially used by climbers when out on multi-day climbs, Bivy camping soon became popular because of its lightweights.

What to Look For When Buying a Bivy Sack?

A bivy sack is small, there is no question of this, and for this reason, many hikers or campers may ask why you would bother when you can find a one-person tent that does the same thing.

Before looking at what you need to know about purchasing a bivy bag, we will first try to answer this question.

Bivy Sack vs. Tent

There is no right or wrong answer in the most basic, and it is down to preference. Both have their plus sides and their downsides, so here, we will highlight these points.

Weight: Single-person tents are getting lighter, yet a superlight bivy will still offer more portability by being lighter and smaller than a tent. A tent will be, on average, double the weight of a bivy.

Comfort: Nearly every bivy suffers from some condensation issues. Tents don’t experience the same problems, and they do offer space to store all your hiking gear, such as boots and backpacks.

Cost: Tents work out cheaper than a bivy, though you may be sacrificing material features such as waterproofing.

Convenience: A bivy winds hands down here. Because these were originally for climbers, you can’t pitch a tent halfway up a mountain. Likewise, you can sleep in any area you wish when using a bivy, whereas they may not be suitable for a tent. Stealth is also another factor, especially if using a camouflage bivy.

Now, here are the factors you have to consider when buying a bivy for hiking.

Hike Length

You do need to consider how you will use your bivy while hiking. If you are on an overnight hike, then a bivy can be the ideal option. If you are away for a couple of days, you can use a superlight bivy with a rain tarp to deliver a superior way of weather protection.

Using this method, you can cut down on weight, and you have somewhere to stash your backpack.

Weight and Size

When you reduce weight, you begin to make compromises in some features unless you spend a fortune to ensure you have a weather-resistant bivy.

Many hikers purchase a bivy to cut down on weight. Many of the hoop models offer headspace, yet you do face a compromise in the packed size because of the poles. While something may be light, if it is cumbersome to carry, then it can be counterproductive in your maneuverability.

With the size of your bivy, you may find some models lack interior space. The outer size, in some cases, doesn’t equate to a more extensive interior. One of the most important things to be sure about is you can easily fit inside.

The models that come with hoops to deliver space around the head and shoulder are often more substantial and thus larger. But, once you move down to the area of the knees and feet, you can find they are still cramped.

Condensation & Waterproofing

Once you have tried a bivy tent compared to a tent, you will find them much warmer, but they can
come with a downside. The breathability of the outer material is vital while trying to stay water-resistant for bad weather.

It is a delicate balance, and manufacturers still struggle to find this with the construction of their bivy sacks. You tend to find high-quality materials such as Gore-Tex fabric that offer the best of both, yet they can still suffer from minimal amounts of condensation.

When searching for your bivy, you will have to consider if you are venturing out in all weathers or strictly be a dry weather hiker and bivy user.

Extra Features

While most of the newer bivy sacks are for hiking use, some still include features as selling points to make them stand out from the competition.

Compression sacks are one of the first so that you can pack away your bivy into the smallest possible size.

Sealed seams ought to be standard, although not every model goes to this extent to deliver waterproofing.

Straps allow you to fasten your bivy to your hiking backpack or fasten it to other areas where it is accessible if you are caught out, and you end up camping in the rain halfway down your trek.

Bug protection is one of the newer features and is most often found on hoop-designed models.

In summary, once you know the use of your bivy, you can quickly narrow down your choices. Not every variant offers what you are looking for, and when you add in your budget, it is evident which models will meet your needs and compares to the best camping tents for one person .
