On multi-day hiking trips, a portable shelter comes in very handy because it allows you to set up camp almost anywhere and whenever you like, instead of having to reach safe places like mountain huts. While tents are definitely more comfortable, if you’re hiking alone, you might find a tent too heavy and voluminous to carry – especially if you’re on the trails for less than three days.
A bivy sack is an excellent alternative choice to a tent on such trips since it is lighter while offering similar weather protection. A high-end bivy sack is twice as the light on average and 30 percent smaller than a high-quality two-person tent (packed size). Not only does it take up significantly less space in your backpack if the weather is against you, but it can also be set up very quickly too.
However, bivy bags are not suitable for longer hiking trips, because they offer very limited comfort/space and often require the backpack to be left outside.
Here I’ve selected and done reviews for the best bivy sacks for hiking, backpacking, and mountaineering. I’ve decided to only list products made of waterproof breathable materials as these provide the best versatility in various conditions and amazing extreme weather protection. I’ve mainly targeted lightweight and well-packable products.
All emergency bivy sacks we will be looking for in the reviews down below will accommodate for only one person, to assure for a more minimalist and better for backpacking design, so be wary if you are searching for something more family orientated.
How To Choose A Bivy Sack?
Having to choose the right bivy sack that has enough space for your sleeping pad, while not having too much weight behind it and being structurally stable is a hard combination to be achieved. However it is crucial part of your bushcraft equipment and a must have item in your arsenal.
The above-mentioned list has objectively one of the best bivy sacks on the market, but you may want to choose another one and to be prepared and to understand the reviews above better, I’m going to list all of the factors that carry the weight of making not only a great but the best bivy sack model for you.
Decide On The 3 Main Types of Bivys
There are three main types of bivy sacks-traditional sacks, face lifters, and bug nets. They all share a similar “slip over your bag” design, but they differ in weight, comfort, purpose, and material.
Traditional sackcloths fit over your sleeping bag, from head to toe. There’s a flap at your head with a zipper that you can leave open on a warm, dry night. Or, when the weather is nasty close, it shut. You’re completely sealed into the bivy sack when you close that flap, much like a coffin. You definitely have to leave a small opening in the zipper so that you can let a little bit of fresh air into the bivy sack and allow your breathing out to condense.
Facelifts enclose your sleeping bag like a traditional bivy sack, but for comfort, these bags have a hoop at the head. This greatly reduces the coffin-like feel of a bivy sack while maintaining the benefits of weight and size. The hoop gives you room to read or check your phone before you crash into the evening.
All you need sometimes is a simple bug net to keep the insects at bay while you’re sleeping. These net bug bivy bags enclose your Bivy bag in a fine mesh fabric that won’t let through even the smallest no-see-um. This bug nets often have a hoop or a pole in the head area so you won’t get bit through the fabric.
Size and Weight
While reducing size and weight is something manufacturers focus on when designing a bivy bag, it still needs to have enough room for you when it’s time to sleep. When talking about dimensions, there are two things you should think about – how large is the sack when you open it and how small it is when packed.
As you had the opportunity to see, most bivies range between 80 and 90 inches in length, with some being even longer. If you are a tall person, you should go for a longer bivy – otherwise, you might not be able to zip it up properly.
Width also varies from one product to another, and it’s different in the shoulder and foot area. Length, width, and also height greatly influence the comfort you’ll be feeling inside. Some people feel a bit claustrophobic when they start using a bivy bag, so it may take some getting used to. You should also be aware that most products won’t allow you to fit your gear inside, so you may consider getting a waterproof backpack.
Some products come with poles, and some don’t. Poles are attached like hoops that pitch the material and form a canopy over you. This gives you significantly more headspace and reduces the feeling of unrest we mentioned because the fabric doesn’t sit on your face when you zip the bag.
When packed, it should take as little space as possible. All the products we listed are very small and lightweight when compressed, but there are still differences between them. If your bivy comes with poles, stakes, or heavier materials, for example, you can count on it being bulkier. It all depends on what your need is and what you are willing to sacrifice to get the smallest package possible.
In addition to the compact package, you also shouldn’t feel the weight of the bag on a long hike. Weight usually ranges from as little as 1 pound to just a bit over 3 pounds. This is somewhat the top limit it’s allowed to have – if the bivy exceeds the weight by much, you might as well consider getting a backpacking tent.
Like size, weight also depends on the accessories and features which come with the sack. If you decide to cut down on weight, make sure you don’t eliminate anything you may need when outside, because lightweight bivy bags aren’t always the best ones.
Bivies come in many shapes and sizes, as already mentioned. They are essential, in some cases, a sheet of waterproof material that gets wrapped around your bag so you won’t be worrying about any rain getting in. On the other hand, under cold weather and harsher conditions, less minimalist designs create more of a cocoon to camp.
The latter type of bivy sack frequently uses pole or hoop structure, creating a mini tent-like atmosphere within the sack. They give you more storage space and room to move around and the ability to easily shed water and snow.
The downside? They aren’t as lightweight, and they are also more expensive as well.
This decision depends on what you plan to use your bivy sack for. If you’re looking for a more permanent tent alternative, you may want to go for something with a pole structure. But if you want a bivy that’s for quick, infrequent trips, a poleless one will probably serve you just fine.
Hikers and mountaineers always strive to have equipment that packs small as it them to pack their backpack more efficiently. In this selection, we only included bivy sacks with small pack size.
All bivy sacks in these reviews are made of waterproof breathing fabrics such as Gore-Tex Respiration Positive Fabric, eVent, and Pertex Shield (these fabrics are also used for rain jacket) or normal ripstop nylon. Waterproof and breathable fabrics differ in weather resistance, breathability, and durability.
3-layer fabrics (consist of the face fabric, membrane, and an inner fabric) are very durable and offer great breathability and rain and snow resistance. Thus, bivy sacks made of 3-layer waterproof and breathable fabrics offer a superb performance but are also quite expensive.
2.5-layer fabrics ( material consists of the face fabric, coating or membrane, and a non-fabric inner layer) are extremely light and offer decent breathability and rain resistance. Bivy sacks made of 2.5-layer waterproof breathing fabrics are therefore very light, but they might occasionally have a buildup of condensation due to the mediocre breathability of the fabric. Ventilation holes/panels might be used to minimize condensation issues.
Due to thicker individual layers, 2-layer fabrics (consisting of a face fabric and coating or a membrane) are heavier. Compared with 2,5- and 3-layer waterproof breathing fabrics, they offer inferior breathability and weather resistance. Bivy bags made of 2-layer fabrics are usually used only as an emergency shelter.
That’s why we didn’t include any in these reviews. Occasionally, they are equipped with ventilation holes to mitigate the problems of condensation that may appear because of the fabric’s poor breathability. They are also very lightweight, but they have not many additional features and more minimalist design.
No matter the number of layers that have been used, any fabric used in portable shelters should be treated with DWR (sustainable water repellant) to repel the water instead of absorbing it. The floors are usually made of ripstop nylon coated with polyurethane for better durability and water resistance.
Bivy sacks can help keep you warm by retaining your body heat inside. The efficiency in this department varies from product to product, mostly depending on the type of material used. You should check what the other users had to say about this to get a clearer picture of what you can expect, especially if you plan to use it in the snow. Also, consider combining it with a winter bag or at least bring a blanket for additional warmth.
Even though this is not the main focus point of bivy sacks, you still need to get a good rest when you use them. Several factors contribute to this, and bivy sacks are becoming better and better. As we mentioned earlier, check that your new product has sufficient length and width for your body frame, and it’s pretty lightweight. It greatly helps if you have some space above your body too. The design can make your user experience better – whether you can set it up quickly, and if you can easily get in and out of the sack. Finally, waterproofing and breathability are key components of your comfort inside, because it’s not very fun to wake up wet and sweaty.
Weather Protection and Condensation Resistance
The weather and condensation resistance of a shelter greatly depends on the fabric. Unfortunately, the two qualities are mutually exclusive to some extent. The higher the breathability of the fabric, the better the condensation resistance as it allows moisture and warm air to escape to the outside.
However, there is no such thing as a highly breathable fabric that is also completely waterproof. Therefore, manufacturers have to find the right ratio between breathability (condensation resistance) and weather resistance to achieve the best functionality.
In general, bivy sacks offer inferior rain and condensation resistance in comparison to double-wall tents (which are equipped with a completely waterproof fly that comes over a breathable canopy), but on the other hand, they are also faster to set up and much lighter. We do not recommend using a bivy sack (or indeed a single-wall tent) in areas that are known for continuous heavy rain.
This is often pointed out as one of the weak points of bivy sacks. Waterproof materials aren’t very breathable, and this becomes even more obvious with bivies. The air can’t circulate, and you might encounter a condensation problem. Droplets of water form on the inner side of your bivy because the vapor has nowhere to go.
For this reason, try to look for products that have mesh panels or special vents that improve circulation and eliminate this problem. If you choose to get a bivy made of Gore-Tex or something similar like a Pertex Shield, it will greatly increase your comfort in this area.
Most bivy sacks are waterproof, but you won’t be able to use each of them in every circumstance. Some are designed for warm weather and insect protection, while you can also get a 3 or 4 season bivy tent if you plan year-round adventures. You need to think about how long you’ll be staying outside and the general weather conditions you’re expecting.
Bivy sacks are the best choice for an overnight stay or even a couple of nights, but if you plan a prolonged stay, you should consider a larger and more comfortable solution, like a 4-season tent, for example. Also, some bivy sacks will be more comfortable in warmer months, while others will keep you nice and cozy in cold weather but make you sweat when it’s warm. Weigh the options and make a choice that suits your hiking and backpacking style.
Perhaps one of the best extra features your bivy can have is a mesh panel (or a complete mesh inner layer). This gives your bivy bug protection when you want to unzip or remove the rainfly while enabling free air circulation and light. You should look for a sack with features similar to this one because nobody enjoys mosquitos buzzing and bugs crawling over you.
Besides, some products have extra features in the form of vents that function even when the fly is completely zipped. Some manufacturers include stakes and guylines, which you can use to stabilize your shelter properly. Finally, some features are added to improve your comfort, like small mesh pockets inside or straps to keep your sleeping pad in place.

Bivy Sacks FAQs
What Is A Bivy Sack?
A bivy sack is a shelter for one person which you sleep in and serves as a more compact and lightweight backpacking alternative to a tent. You can easily take it anywhere, and you’ll always have something to keep you dry and warm at night.
Why Should I Use A Bivy Sack Instead Of A Tent?
This is a great choice if you need something to sleep in, but you want to save backpacking space and cut weight when packing. It’s much lighter and smaller than any tent out there. It’s also a good emergency shelter you can set up quickly, faster than most tents. Keep in mind that because of the size it isn’t very useful for hanging out inside like you would do in a tent.
How Do I Prevent Condensation In My Bivy Sack?
When we discussed breathability, you can have less condensation inside if you choose a sack with good design and material choice. Make sure your new bivy has mesh panels, and unless there is heavy rain, you should leave the zipper open so the vapor can escape instead of making condensation inside. Like we said, dedicated vents can help reduce the condensation.
How Do I Wash My Bivy Sack?
There will come a time when you need to clean your sack before the next use. Luckily, most bivy sacks can be washed in a machine, but you should always check the label or instructions. Whether you choose to wash it in a machine or by hand, always rinse it off properly. Some can go in a tumble dryer, while others should be left to air dry. Make sure it’s completely dry before packing it. Otherwise, you may risk mold or weird smells.
The best bivy sacks are the ones that you can feel comfortable in, the ones that have the best and most comfortable sleeping pad, the ones that have the best breathability, and the ones that aren’t to keen on the whole weight thing.
But all of that is irrelevant at the end of the day because you can compare statistics and all sorts of numbers and marketing slogans and technical jargon because the best bivy sack will be the one that you can relax and feel comfortable in. All other things aren’t that important.
