Frequently Asked Questions (FAQs)

1. What is the lightest bivy?

The Bristlecone is one of the lightest bivy sacks on our list, weighing a mere 7.5 ounces for a standard-sized sack. Even though it is light, you don't have to sacrifice quality or features.

2. How heavy is a bivvy bag?

The paratec material is soft to the touch and lightweight, meaning the bivvy has a total weight of only 340g. Length is 230cm and so can take a >6ft tall male with room for a sleeping bag and smallish rucksack inside. Packed up, the bivvy takes up about 14 x 10 cm, so not too bulky at all.

3. Are bivy sacks worth it?

The ultra-compact nature of bivies makes them a valuable assets when shedding weight. Some stuff down to the size of a burrito (the food kind), disappearing in bikepacking bags and small alpine packs. With a smaller pack you can cover more miles and more easily traverse through technical terrain.

4. How do I choose a bivvy bag?

If you're going to go for cheap and cheerful to save some pennies, just make sure the bivvy bag you choose is waterproof and breathable. If you don't, you'll likely end up with a damp or wet sleeping bag which is going to result in an uncomfortable night's sleep (and said bivvy bag would probably never get used again).
