The leberna large bivy sack gives the top-tier sack a run for their money by offering flagship specs at a much more affordable price. The Leberna emergency survival mylar thermal sleeping bag can increase your chances of survival in all weather, all seasons and all circumstances. It is replacing/complementing and it's a good weight for a bag, and light (not ultra light) backpacking.

The survival frog large bivy sack's superior materials makes sure that it ages well with use. The sleeping bag is essentially a high quality, reflective foil sleeping bag. It's a wonderfully small sleeping bag, tarp, water catcher, whatever is needed. It's a person-sized, heavy-duty bag designed to keep out ground dampness, the rain, and block the wind. The material ensures these sacks are tear-resistant, windproof, and waterproof. This is just a foil layer intended for use in emergency cases or to add an extra layer of warmth in your sleeping bag.

It reflects body heat well but keep a liner or sheet handy if you plan to use as a camping alternative due to the capacity to sweat with nowhere for the moisture to go. It is designed to aide in maintaining core temperature when outdoor elements are working against you. It is used for warmth at an outdoor play. The bag itself is a tough kind of plastic, not really "crunchy", more the consistency of a big candy wrapper.
