Top 5 tips for choosing a bivi bag
1. Long Term Regular Usage
If you are looking to purchase a bivi bag that will last the distance then go for something in the higher price margin preferably opt for a goretex bivi bag as this material will last you a long time and may save you money over the long term.
2. Short Term Irregular Usage
When looking to purchase a bivi bag for the occasional use over a short period of time or a single trip i would recommend going for a cheaper option as there are many suitable bags that will offer good protection for a lower price and give you greater value for money.
3. What Conditions are you Likely to Encounter
Now althougth the author recommended that a cheaper bag may be easier on your wallet you must take into consideration what kind of weather conditions you will face. Even if you are only planning on a single trip, if it is possible you will face extreme conditions then always opt for a bag that will give you the protection you need. It may sound obvious but this is not a time for penny pinching, be in no doubt that a good, preferably, goretex bivi bag will keep you warm and dry, protecting you from the elements in even the harshest of weather.
4. Bivi Bag or Bivi Tent
A bivi tent or hooped bivi can provide extra space for storage and will not be as claustrophobic also allowing for an easier nights sleep, it can also have added protection from internal moisture build up as the sides and roof of the bag will not have direct contact with your body. However, if you are looking for concealment then go for a more traditional bivi bag as you will stand out more in a bivi tent as it is of a larger size and so will be more clearly visible and take up more room. A bivi tent, althougth easy to constrcut will take longer than simply getting into your bivi bag. This may also be taken into consideration if time is an important factor to you.
5. Weight and Compatibility
If added weight and/or space is an issue then look for a bag that specifically states that it is ultra lightweight and will compact to a good size. Generally goretex bivi bags will do this job well but there are other materials which also offer this practicality.
