No lightweight!
This is a big, synthetic filled bag from the 1990's, with a 1/2 length central (ventral?) zip, in turn covered by a substantial padded and velcro'd flap. Draw cord and padded hood..
Heavy around 2.5 kg, and big although a compression bag will reduce this considerably.
It is a good 3-4 season bag, rated on its own to about -10/15c . With a liner, available for about a fiver, and and decent bivvi, you have a system that will keep you warm and snug, wherever, however.
Pros: Robust, Available in different sizes, Adaptable, Warm, Cheap
Cons: Heavy, Bulky
Would recommend: Yes
