Ultra light travel is becoming popular these days with more and more people heading out to the remote parts of this world on adventure trips. When you travel hard and far, you don’t want to be carrying to much weight. Rather than carry a tent and sleeping bag, why not consider getting the best portable sleeping solution: a bivy sack.
A bivy sack is basically a specially bag that you sleep in. The bivy sack is water proof and should protect you from getting wet – either from the rain or from a soggy ground. In principle, a bivy sack is all weatherproof, but in reality it depends on the quality of the bivy sack.
Quality is a big deal when it comes to bivy sacks. If you opt to save money and buy a cheap bivy sack, you are likely going to get wet in extreme weather conditions. Cheap bivy sacks may leak water through zippers or they may not be that breathable which leads to the build-up of condensation inside the bivy sack.
Condensation is a big deal. What can happen is that condensation can stick to the sides of your bivy sack and leak water over you. This means you could end up very wet inside. Bivvy sacks are designed to help keep you warm (roughly 10C warmer inside the bivy sack area than outside), but if you get wet a lot of that warmth benefit is eliminated.
To avoid problems with condensation build-up, you should look at getting a bivy sack made from breathable materials like Goretex. This material is more expensive, but you can save yourself a lot of headache by buying a breathable bivy sack.
The best place to buy a bivy sack is online. There are quite a few online retailers out there that offer sports gear like sleeping bags and bivy sacks. Buy one online and save money.
