Bivy sack is a short form for “bivouac sack.” It was made to serve climbers who wanted lightweight emergency weather protection for sleeping bags during multiple-day ascents, especially on big walls.

Previously, bivy sacks were little more than waterproof nylon slipcovers for sleeping bags. They were suitable for shielding sleeping bags from rain and not so good when circulating vapour produced by body heat.

A bivy sack’s head opening indicates moisture can potentially find its way inside. You can lessen that risk by pulling the head holes drawstring very snugly.

Tips for choosing the right bivy sacks for you

While buying a bivy bag, there are specific considerations you need to make before choosing a bivy sack. These include the type of bags, where you will be taking them, and many more.

Where will you be taking it

A bivy sack can be a good product because of its versatility. Even high in cold mountains or a summer meadow, a bivy gives a lighter-weight alternative shelter.

What you are sheltering from becomes the factor to consider before choosing the best product for your needs.

Some things you need to ensure before buying the best bivy sacks in Spain are: Will the place be full of mosquitoes? Are thunderstorms predicted? How warm are the temps to be, and how much warmer will that sack make a sleeping bag?

Enough space

Bivy sacks usually offer just sufficient space for one person. Some allow you to suspend the material above the head, which reduces the claustrophobic effect of the small shelter and thus increases your comfort.

There are two different methods to suspend the material above the head area: The pole and the flexible wire systems.

The pole system is very dependable but requires additional work when setting up the bivy sack because the pole must be inserted in the sleeve and secured.

The flexible wire system is common on bivy sacks with low head height. The wire in the head area extends automatically when the product is unpacked and thus negligibly suspends the fabric above the head.

Weather and Condensation Resistance

Besides the weather, the condensation resistance of the best bivy sacks in Spain is immensely dependent on the fabric. Unfortunately, the two qualities are mutually exclusive to some scope.

The higher the breathability of the fabric, the better the condensation resistance as it lets moisture and warm air escape to the outside.

However, there is no such thing as a highly breathable material that is also completely waterproof. Therefore, manufacturers must find the correct ratio between breathability and weather resistance to reach the best functionality.

Advantages of using bivy sacks

Light and Portable

The biggest benefit of using a bivy sack over a tent is that they are very lightweight and portable. It is beneficial for hikers and climbers looking to lower weight in their pack.

They usually weigh less than tents, hammocks, or any other type of shelter other than maybe a tarp which covers you from rain but doesn’t protect you against the wind and the wilderness from the sides.

Waterproof and Bug Proof

Modern technology has created some great fabrics. In addition to being lightweight, their materials are waterproof.

There are typically two different materials used in constructing the best bivy sacks in Spain. The top one is lightweight nylon and the base level that feels the ground is a heavier material that can withstand a bit of abuse.

Lastly, an enclosed shelter will rid you of mosquitoes and bugs. Some models are with a bug net on your face that lets you breathe outside of the shelter while reducing condensation.

Easy to Find a Campsite

Another advantage is that it is easy to locate and set up your campsite. Since you only need to find a space the size of a sleeping bag, you don’t need to find a site large enough with the proper ground to pitch a tent. It will help you spend more time relishing your trip rather than working in the camp.

Insulation

Another benefit is the insulation they give. You can expect five to ten degrees of extra insulation from your bivy sack while you sleep.

Don’t require a lot of space

The best bivy sacks in Spain do not need a lot of space. It is easy to find a spot to lay a bivy sack at night since it only requires as much space as your sleeping bag or quilt. You need a flat surface big enough for you to lie down on. Bivy won’t need securing to the ground as tents need. There are no guidelines for setting up tent stakes to pound into the ground.
