Imagine you are going for a walk in the woods and suddenly a storm appears. There’s no shelter, and you have nowhere to hide. It’s already dark, and it’s raining so hard you can’t find your way back…so you have to wait until the rain stops, or until the sun rises. What do you, then? You use your bivy sack and spend the night knowing your safe!

Mountaineers, soldiers, and scouts have been using military bivvy sacks for years.

Military Bivy Sacks

These items are easy to set up, highly portable, and lightweight, and help you move fast and stay protected in harsh elements. Nowadays, modern materials, such as Gore-tex, for example, have made these units very reliable, and most importantly, breathable.

However, there are different things you need to consider before buying a military bivy, and today we are here to help you! We’ve gathered the best products online, and we really hope you will find our reviews useful and decide on the ideal gore-tex bivy, mylar bivy, or polyester bivy for you. Let’s get started!

Now, if you were impressed with how lightweight our first suggestion was, wait until you hear the size of this one. It weighs only 4.8 ounces and, when rolled, can also fit in the palm of your hand (which is the whole purpose of bivvy bags).

The greatest part is that you get a paracord drawstring and high-decibel emergency whistle that will help you call for help if you get lost in the woods, for example.

This is another lightweight bivouac sack with nice zipper closure, high levels of water resistance, and a rugged design.

The green color of the bivy sack is smartly chosen to help you blend with your surroundings, and since the bivy itself is made of quality polyester, it is incredibly durable and will surprise you with its strength.

What we liked the most about this suggestion was the drawstring that was actually a para-tinder paracord. We loved it since you could use it to tie down your gear or even start a fire by exposing the tinder cord. The bivy sack also comes with a 120-decibel whistle and a carabiner you could clip to your backpack.

Primacare HB-10 Emergency Thermal Blanket

 

Here’s a suggestion that’s a bit different since it is not exactly a bivy bag but more of an emergency blanket. If you want to get a great camping experience and feel safe no matter the weather, this thermal Primacare HB thermal blanket is one of the units you must definitely consider buying.

This is actually a 10-pack, so you’ll get 10 thermal blankets that are waterproof and provide excellent insulation. Each item is made of foil and Mylar, and that means it reflects your body heat or deflects heat from the sun. How cool is that?

The Primacare HB mylar blanket is 84″ wide and 52″ long, and that was one of the reasons we liked it so much. It provided enough space for us to feel comfortable while we were testing it, and it is also easy to clean once you’ve used it. This unit is undoubtedly a must-have for your first aid kit.

This bivy sack offers excellent breathability, yet it keeps you warm and reflects your body heat to keep you safe even in the harshest of environments. Besides well-ventilated, this bivy sack is also well-built.

You get to choose from two different colors, which is also a nice thing the manufacturer has thought about. The dimensions of this bivy sack are 31.5 in (W) x 92.5 in (L) x 11.8in (H)

The Escape bivy is an excellent survival sleeping bag that prevents heat loss and keeps you warm by offering 70% of heat reflectivity. Its construction is very durable since it is made of hard-wearing fabric that is quiet and will not shred to pieces if punctured.

This Survive Outdoors Longer bivy blanket has a weight of 8.5 ounces, which is somewhat heavier than some of our other suggestions of bivy sacks, but it is just as sturdy and efficient. It measures 84 x 31 inches and has a drawstring hood and taped seams that offer excellent waterproofness.

We found the breathable fabric this bivy sack is made of to be a great advantage since it lets consideration escape while keeping snow, rain, and wind out. The size zip is also well-made.

The bottom line is, this bivy sack can withstand heavy use as an emergency sleep system or a standalone sleeping bag. It is the perfect carry sack to take with you wherever you go!

Tennier Military Modular Sleep System

 

Now, this is an interesting suggestion! The Tennier military modular sleep system includes four different items- ICW bag, Patrol bag, sack, and a gore-tex bivy cover. All of the parts are manufactured in the USA, and since this is also a military issue used by the US army, you can be sure that it can definitely save your life even in cold temperatures.

The Patrol bag has a reversible double-pull slider that provides excellent ventilation. It is rated for temperatures 50 to 30°, and it also features a non-locking slide fastener, a draft flap, and an adjustable hood.

The intermediate cold weather sleeping bag, on the other hand, has an anatomically designed foot box, sewn insulation, and a quilted chest collar that will stop the air from drafting up and down the hood. It is suitable for climates between 30 to -10°.

We also liked the bivy cover for it is very durable, and when you combine it with the ICW and Petrol bags, the whole system becomes suitable for climates down to -50°. You’ll also need proper clothing, of course, but the fact that it is compressible to one cubic foot is very impressive.

The nylon webbing straps are easily adjusted with the help of ladder lock buckles, and the whole circumference of the bag is sewn with reinforcement webbing.
