Tact Bivvy Emergency Sleeping Bag Features

Windproof and Waterproof

Bivvy defends all consumer from difficult situations, developed to hold the worst, coolest weather out of your pack. The Survival Frog TACT Bivvy is taped at the seams to prevent any winter temperatures. This fabric is designed to protect astronaut in outdoor space. This product is water-resistant and wind resistant and the best design for those at risk.

Highly Durable

The Tact Bivvy has a specific Mylar cover, which uses a technology called Heatsheets, designed to avoid tears and heat escape. This unique coating avoids tears and is very long and long-lasting. While the bag rolls, scraps, cuts, or unintentionally puts the sharp items in contact, it also does not snap or cut. It also makes sure that the heat in the bag is at all times locked in it.


If you need a night of great warmth and relaxation, see Helium or Alpine outdoor study. You sound as though nothing would touch you next to the Frog Tact. For the unbelievable few the Frog Tact is. It accumulated more dampness than every other model, there was no closing mechanism and in heavy wind it was really noisy and crunchy. Both these aspects have been sliced into our sleep night. The point is not hidden that it’s an extremely minimalist bivy, it’s better than nothing. The rain stayed away from us, and although the wind and the rain were a lot of noise, it was enough to protect the elements.


The lightest bivy that we reviewed was totally. The makers of this bag seem to want a bivy, the lightest it can be, without any addition. It’s only as easy as 128 g or 0.28 lbs. For this tiny weight, what will you get? It arrives with a waterproof bag and a simple polyester film bivy. No closing mechanism, including a zipper or a rope, is available and, very simply, the content is insufficiently sturdy for these extras.
