Best Bivy Sacks Buying Guide

As you are sure to have noticed, the best bivy sacks come in a wide range of different styles. While this provides you with plenty of choice, it can help make selecting the perfect model a little tricky. Here are some of the key factors that you should bear in mind when checking out the top options.

  • Weatherproofing

The last thing you want when setting up an emergency camp is to get attacked by the elements. Therefore, it is essential that the bivy sack you choose is highly waterproof. The ‘hydrostatic head’ (HH) scale has been created as a guide to perfect waterproofing.

The higher the HH number, the more waterproof your bivy sack will be, with the maximum being 20,000 HH. Ideally, you need to search for a bivy sack that is at least 12,000 HH. If your bivy sack is waterproof, it is also likely to provide you with enhanced protection against the other elements.

  • Ventilation

If you have to spend several hours or even days in your bivy sack, it could quickly become hot and stuffy. Therefore, good ventilation is absolutely essential. Search for a model that is made from a material such as Gore-tex, eVent, or Pertex.

If the weather is especially warm, you will want to choose a bivy sack that comes with mesh panels. You should be able to unzip the outer material while still being protected by the mesh. This will allow the air to circulate without allowing bugs to enter.

  • The Weight Factor

Like with all types of outdoor gear, you will want your bivy sack to be as light as possible. However, you will not want to compromise when it comes to durability. Choosing a model that is compact as possible is also essential if you are planning on hiking long distances.
