The Role Of An Emergency Bivvy In Your Survival Kit
The word ‘bivvy’ is a shorter version of the full term which is bivouac. This basically refers to a makeshift shelter or form of protecting yourself from the elements. When out in the wild, the more robust your shelter, the better. Naturally, a cabin or survival tent would be ideal, but sometimes those luxuries aren’t available.
We have previously looked at ways you can plan to protect your family from natural disasters, and having supplies such as the Tact Bivvy can be a great way to add to this protection.
A bivvy is a great addition to your survival kit, as they are generally durable and portable, meaning they can come in handy during a tough spot. If you find yourself in a survival situation, staying warm is vital, especially in locations with low temperatures.
You can find yourself succumbing to the cold and hypothermia before you know it if you’re not prepared, but a bivvy can help to give you a fighting chance to avoid this outcome.
In the past, we have covered 5 tools you should have included in your survival kit, and this bivvy fits really well into this list.

About The Brand
Survival Frog is a brand we feature a lot, and there are many reasons for that. It’s mainly because they have consistently proven themselves to create quality survival products for a wide range of situations and scenarios.
They started in 2009, and since then their operation has grown by a large margin. Survival Frog not only produces their own quality products, but they also distribute other top brands. When developing their products, they get the advice of experts and specialists to make sure that each product is high quality and effective for survival situations.
The Tact Bivvy is no exception when it comes to this high standard of quality, and we will see why that is as we take a look at the main features and benefits on offer with this product.
Key Features And Benefits
- Ultralight 4.7 oz: The last thing you want from a survival tool is for it to be large and cumbersome to carry around. Keeping things light is important to maintain your energy as you travel, and the Tact Bivvy certainly delivers there. It weighs a minuscule 4.7 oz, meaning you’ll probably barely notice you’re carrying it.
- HeatEcho™ Technology Reflects 90% Of Your Body’s Heat Back To You: When you have to survive in harsh cold conditions, maintaining your body temperature can become a vital priority. You can lose your body heat rapidly if you’re not well protected, and that can lead to hyperthermia and other cold-related injuries. The Tact Bivvy features innovative HeatEcho™ technology that will help you to maintain 90% of your existing body heat.
- 100% Waterproof, Tear-Resistant, and Windproof
If out in the wild, weather conditions can be your biggest enemy. Rain, snow, or heavy winds, for example, can make survival even more difficult. The Tact Bivvy is completely waterproof, tear-resistant, and windproof, which can help you stay warm and protected in harsh weather.
It also generally means that the bivvy should be safe from damage even if you’re enduring harsh conditions.
- Para-tinder Paracord: The bivvy comes in a special sack for easy transportation, and it’s secured with a 10-inch drawstring cord. This is no ordinary cord, however. If you expose the inner core of the drawstring, there is a special tinder material that can be used to start a fire in an emergency situation.
- 120 Decibel Whistle: If you’re in a dire situation, hopefully, rescue will be looking for you soon. If you’ve been lost for a few days and are too weak to call out or if you’re in a remote location, you can use the attached 120-decibel whistle.This can be used to attract the attention of rescue efforts and could prove to be a real lifesaver.
- 100% Money Back Guarantee: We highly doubt you will need to make use of this, but if you are not satisfied with your purchase, you can contact Survival Frog for a no questions asked refund. You have 6 months to take advantage of this refund, and this shows how confident the company is in its products.

Setting up your Tact Bivvy is about as easy as can be. It merely needs to be removed from the casing and then unfolded. Once it has been unfolded, you can either use it as is as an emergency sleeping bag, inside your regular sleeping bag, or in any other situation you may need it for.
Then, you need merely fold it up and pack it back in the casing to have it ready for another day.

The waterproof, windproof, and tear-resistant elements of the design mean that it will be useful and convenient in a wide range of survival situations.

In terms of downsides, it’s hard to think of any. The simple nature of the bivvy means there’s not much that can go wrong. The lightweight and compact nature of the bivvy may make it easy to accidentally not pack it, but that is quite a stretch in terms of a downside.
Overall, for what it aims to do, we feel the Tact Bivvy is completely successful.
FAQ
Do Emergency Bivvy Sacks Work?
A bivvy can be very effective when used to protect you from harsh weather or the elements in general.
