Quite a decent sleeping bag.

It arrived faster than I expected, it looks good, the color and size (I have 178 cm and 100 kg) fit. I’ll test as soon as the temperatures drop.
This is a nice sleeping bag and is also a great value. I purchased the version containing 1000 grams of goose down. The total weight is 3.3 pounds, just like they say on the web site. The quality is very good. The sleeping bag puffs up to between 5 and 6 inches thick so it should provide plenty of insulation. I am 5 feet 10 inches tall and there is room to spare. I am confident that this sleeping bag will keep me warm while winter camping in Vermont.
