8 Best Bivy Sacks 2018 (An Unbiased List to Add to Your Wishlist)

Note that this list is not arranged in any order of preference. All of these tents are equally capable of ensuring that you have a pleasant trip. For your benefit, we have pronounced the pros and cons of each of the best bivy sacks that we have described as well as a final verdict.

Outdoor Research Alpine Bivy Sack

Outdoor Research is considered to be one of the most impactful and important manufacturers of trekking and camping equipment. This is true in the case of bivouac sacks too as demonstrated by the Outdoor Research Alpine Bivy. This is one of the most popular bivy sacks among hikers and backpackers. This is due to its fantastic and durable construction but, at the same time, is also extremely lightweight: at a mere 2 pounds, it is lighter than the average bivy sack.

Outdoor Research Alpine BivyThe first thing that we were most impressed by was the 3-layer Gore-Tex Respiration Positive fabric. This offers a superb construction material alongside a wonderfully airy and excellently breathable. Such a material makes this one of the toughest and most durable bivy tents in the business currently. This fabric also offers a superior degree of tear and abrasion resistance. The weather protection factor is also excellent.

Thanks to the high-quality fabric, there are considerably lesser instances of condensation forming inside the sacks themselves. The resilient nylon floor design makes it considerably stronger and more waterproof. The Outdoor Research Alpine bivy sack also has some features which are nicely thought of and come in handy from time to time. Since it comes with a pole, you can suspend the fabric above your head, for example. You can also secure the outside sleeve using the Velcro closures which come with it. The sleeping pad straps and the no-see-um mesh are some of the other features which we like. Overall, a great option as far as lightweight bivy sacks are concerned.

PROS:
  • Lightweight and durable construction
  • Easy to carry around even at high altitudes
  • Condensation resistance is remarkable
  • Weather protection factor is good

CONS:
  • The zippers inside of the bivy could have been better
  • The no-see-um mesh also needs some minor improvements

Verdict: Overall, this item from Outdoor Research is pretty much our go-to bivy sack for all seasons. It is extremely tough and durable, full of features, resistant to scratches and abrasions, and waterproof. It is also extremely lightweight and is thus a joy to carry around. This bivy sack is a must-buy.

Rab Ridge Raider Bivy

This particular sack is definitely one of our most favorite bivys. This is clearly the biggest bivy sack on this list as the dimensions are significantly bigger than the previous entry by Outdoor Research. By dimensions, we mean the length and width and height. These dimensions also ensure that the company has to manufacture only one size and can focus on a single, seminal model. The sack is also extremely lightweight and durable.

Rab Ridge Raider BivyThe very first thing that struck us when we caught hold of the Ridge Raider bivy sack was that it was one of the top bivy sacks 2018. The ultra-tough construction material used in its design. The upper part of the sack is manufactured using 3-layer 40-denier eVent fabric, which is a proprietary fabric designed by the company. Such a fabrication material also ensures that the bivy is both soft as well as breathable, to speak nothing of ventilation.

The abrasion-resistant nylon flooring material also aids in the durability factor of this sack. This very specific sack also comes with a DAC Pressfit pole which allows you to suspend the material right over the head. A total internal height of 58 centimeters is on offer when the material is suspended. This means that, like we said earlier, this is easily one of the largest bivy sacks in business. For such a light and portable bivy, this amount of space is definitely worth looking into.

The pole comes in the sack’s external sleeve and can thus be used to secure the sack with stakes and keep it upright. Onboard are several handpicked features like a decent six stake loops besides a no-see-um mesh door which is designed to keep all the bugs out. These factors also aid in elevating the ventilation of the sack.

PROS:
  • Lightweight and easily portable
  • Bugproof nature is better than most comparable bivys
  • Abrasion-resistant flooring material

CONS:
  • Can get too cold for comfort at times

Verdict: At the end of the day, this still remains one of the most popular and durable bivy sacks. While comparisons with its other competitors are inevitable, it is also true that this is the roomiest sack we have had the good fortune of owning. Together with the fact that this model is smaller than most one-person tents and is slightly bigger than most comparable bivy sacks, you get the picture.

Snugpak Stratosphere Bivy Sack

These one-person bivy sacks are precisely what one needs when they go on a trek or a camping trip. Given that such bivy tents are available from a lot of manufacturers in the market, what makes this product special is the fact that this model is sturdier and more comfortable than most comparable products.

Snugpak Stratosphere Bivy SackThe first time we used this product, we were in the Florida swamps. We were looking for an ultralight sleeping system and this was then the best product available. The design of the Stratosphere is rather catchy and is uniquely positioned when style and substance come together.

Given that this bivy sack definitely offers increased breathability and all-around ventilation, it can be assumed that no occupant of this sack will ever suffer from claustrophobia. We especially liked the roll away mosquito net that comes with this model and it is likely that this sack will gain some extra marks in the looks department as well.

All the seams of this bivy sack are sealed and the model also comes with its own aluminum screw lock-tips. Overall, a value for money one-person personal bivy.

PROS:
  • Lightweight and waterproof
  • Taped and sealed seams
  • Full-length side zip is a breeze to use

CONS:
  • Not entirely water resistant, merely waterproof

Verdict: Overall, this model is a great buy for those who wish to have their own bivy sack but who regard their one-person tents as too big to use. Being lightweight and portable, this model also makes it to our lightest bivy sacks list. Buy it for the comfort it ensures.

Woodland Camouflage Waterproof Bivy

This model has been included on this list as the best affordable lightweight bivy sack. We have gone on several trips over the last few years covering several hundred miles. This item has yet to disappoint us. Last month, we were in the Grand Canyon backcountry and, on a night with heavy rains, this Woodland Camouflage model again proved its worth.

Woodland Camouflage Waterproof BivyAt its core, this is basically a 3-piece system which is made in the semi-mummy style. The chest and the arm portions are especially snug and the bivy is very warm overall. Like we mentioned, we were caught out in the rain and we were left unscathed. This item brings its waterproof game to a whole new level. Made with Gore-Tex, this is one of the most affordable bivy sacks on this list.

The same Gore-Tex design also makes this model ideal for rough use too. This material has proven itself to be a rather moisture-vapor-permeable material too. Indeed, it is extremely well-ventilated and the material lends itself to rough usage on a regular, if not a daily, basis.

Weighing in at less than 3 pounds, this best bivy sack 2018 nominee is also a member of the Military Modular Sleep System. Overall, this provides value for money and provides decent comfort and airy environments to sleep in. It could have been made a bit more bugproof, however.

PROS:
  • Comfortable nature with a snug fit
  • Incredibly tough design
  • Made with moisture-vapor-permeable material
  • Lightweight

CONS:
  • The item’s bugproof nature needs some much-needed improvements

Winterial Single Person Personal Bivy Tent

The next product on this list of the top bivy sacks is this entry from Winterial. Of course, any self-respecting list of hiking and trekking equipment is incomplete without at least one product manufactured by Winterial. Although the company classifies this as a bivy tent, it is more of a personal bivy sack that is ideal for 1.5 person camping.

Winterial Single Person Personal Bivy TentThis single-person tent-cum- bivy sack is lightweight and can be used by a single individual. It is also very windproof and waterproof in its nature. The well-ventilated bivy goes toe to toe with some of the best 3-season bivy sacks and tents and has clearly made its mark. There is a well-ventilated roof mesh that not only makes the entity airy, it also keeps it remarkably bugfree.

There is a large zippered door that lets the occupant in and out. This way, there are not too many zippers to bother with. When it comes to the Winterial Bivy tent review, we must advise you to follow the instruction manual very carefully. When in warmer weathers, you can use this item without the fly attached. Once it starts raining or the weather takes a turn for the worse, this item can also help you stay clean and dry with the rain fly attached securely.

A fantastic addition to the list of the best budget bivy sacks.

PROS:
  • Lightweight and easy to carry
  • Well-ventilated
  • Ideal for more than one person/1.5-person camping
  • Usable even in wet weathers

  • Not too ideal for use in warmer weathers
  • Not too good to use in the wild

Verdict: Overall, this is one of the best bivy sacks. This wonderful item weighs a mere 3 pounds. It is expected to become even more popular when the two rival genres- of bivys and tents- merge. This item is also equipped with its own stakes which can be used to pin it to the ground. We expect this bivy tent to be sturdier than most comparable bivys.

The last item on our list is also manufactured by the company whose product came in second. This highly distinguishable yellow bivy sack is comfort and style molded into one entity.

Best Bivy Sacks 2018 Buying Guides

Follow these simple instructions and rules to find out which bivy sack will suit you the best. Almost all of the listed best bivy sacks are specialized products, so you need to find the correct one.

Duration of the outing (Click to Enlarge)

The first point is of extraordinary importance. How long will you be gone and where to? Will you be in a group of people or will you be alone or in a smaller group of individuals? If the answer lies in the first option, you may consider buying a sleeping bag. We have an updated compilation of the best sleeping bag liners on this list. If you have more people in the group, you will also have more people to share the load with. This will increase your options: instead of bivy sacks, you can also opt for one-man tents.

Besides, it is also important to remember where you are going to go camping. Are you going somewhere it is going to be very cold? Or do you expect to go somewhere where the temperatures are slightly more moderate? Either way, you will have to remember that most top bivy sacks are manufactured keeping in mind the colder weathers in mind. Not all of these sacks are ideal for use in a warmer or a more tropical climate. Choose wisely before you end up buying one. Some research on the area you are heading to is in good order.

Weight (Click to Enlarge)

The weight we are talking about here is not only of the sack itself but how much extra weight it would contribute to the hiker’s backpack. Weight is a defining factor when choosing all great outdoor equipment and the bivy sacks are also pretty important. If the area where you are going has a fairly even terrain with no great altitudes to be climbed, you might need to ensure if a more weighty bivy sack will suit you. This is because on any high-altitude trip, the weight factor has to remain low and this thumb rule applies here as well.

Some bivy sacks come with a hoop and therefore a pole. These extra features increase the weight of the overall item. When it comes to lightweight bivies, there are a lot of different models which deserve your attention. It is best to spend some time looking up the company’s description of the product that they are selling.

Space (Click to Enlarge)

Space, in this case, is as important as the weight factor. In this case, the space factor has two aspects: one is the available space inside the bivy itself. This is as important as any other factor because of the bivy sack should not be the cause of claustrophobia. Space here is also a factor which should be kept in mind when packing the ideal backpack. One of the most important aspects of the bivy sack is that it is lightweight and occupies less space. This is why this is important here as well.

Waterproofing and Condensation Factors (Click to Enlarge)

How waterproof a bivy tent is, and how well it withstands outside condensation, are also factors that need to be considered when buying a bivy sack. If such an item is not waterproof, it is absolutely worthless. Note that being waterproof and water-resistant are not the same. While most bivy tents are waterproof, not too many are water-resistant.

When buying a bivy tent, make sure that you review the condensation resistance factor as well. This is essential in ensuring that the user does not get too cold in the outdoors while sleeping or nestling inside such a sack.

Wrap up

Hopefully, this updated list of the best bivy sacks 2018 will come to your aid when you are making a purchase decision. Some of the top bivy sacks can be pretty expensive, so make sure you check out the bivy sack reviews before pouncing on one. Do check back for more updates.

    So I just read your” best bivys for 2018″and enjoyed the information.The problem is that I bought a Sierra Designs Zagori bivy a few years ago for a bike camping trip. I’ve only used it a few times due to the condensation factor. ( I didn’t know at the time that this could be a factor.) So in searching the web for how to deal with this problem, I happened onto your article.The problem is that the condensation comes from my body heat. It’s ventilated pretty at the head/shoulders area so I don’t think it’s from my breath. In the morning, the sleeping bag is damp/wet. I was hoping you could share some wisdom on how best to deal with this problem. Thanks
