The material in appearance is Oxford, impregnated with polyurethane. The heat is quite flexible. I did not check the cold yet. Quite a strange decision: on the inside of the neck there is a transparent film made of thin PVC or something similar. Apparently, this should improve tightness. The seams are glued very cordially-sticks out the extruded glue. The accessories are written that D-Flex, but it looks very not high quality. However, on the tent from this manufacturer I have the same. Looks terrible, but it seems to work. There are 2 pockets-internal and external. I'll check the tightness later. Weight about 570 grams. General assessment for I bought it for $24. It seems to be expensive for such a product
