“Is this really a distinct product from the Marmot 25 degree Sorcerer Jr also for sale? Both are listed at the same fill weight and same total weight, but this one has a substantially colder termperature rating. And no reviews to go on. :( Thanks!”

It shows that they are 2 different model numbers, but how can the weight and stuff size be exactly the same as the 25 degree version. I think the original question still needs to be answered. Is this one heavier than the 25 degree, or is the 25 degree lighter than the specs. One of the specs is wrong, yes?
