Especialidades JA/Campamento/Sacos de dormir

Rectangular

El saco de dormir rectangular es probablemente el más común y son populares para el uso ligero. No es adecuado para viajar con mochila, ya que proporciona la menor cantidad de calor y la mayor cantidad de peso. Como su nombre indica, tiene una forma de rectángulo. Aunque hace que sea cómodo y espacioso, la abertura ancha en la parte de los pies es una fuente grande de pérdida de calor. A diferencia de un saco de dormir estilo momia, que no tiene una capucha que se puede extraer alrededor de la cabeza para retener el calor.

Mummy Bag

The mummy bag is shaped like a sarcophagus. It is narrow at the feet (but tall there to allow just enough room for the feet), tapers at the waist, widens again at the shoulders, and then tapers down near the head. The top is very much like the hood of a winter coat, complete with drawstrings to close up the gap and keep heat in. Because they conform so well to the human shape, there is very little wasted space inside. This is good because your body has to heat all that space, and because the extra insulation and material thusly removed does not have to be carried (meaning it's lighter).

Barrel Bag

The barrel bag is a modified mummy bag. It is roomier than the mummy bag and provides almost the same warmth at the cost of additional weight.
