I have not used that specific bag. I have used Sea to Summit's traverse bag. Totally different design, but they know how to make a bag. The coldest version of the bag you are talking about is only a 28 degree bag. Some might say it is not warm enough for a do it all 3 season bag, but you may be able to make it work. If you are looking for an extremely lightweight bag but want to use it in late September as well, I would look at Z packs sleeping bags. They are around the same price as the micro, but way lighter. The only thing is they do not have a hood it is more of quilt type. I have a 20 degree long version, (up to 6'2") I am 5'11" and I can snuggle up in it well enough to cover my head and stick my nose and mouth out. Mine is a wide, long and weighs 20 oz. They now offer a 10 degree bag for a few ounces more. Top quality construction and Joe has excellent customer service. I will be going on a 3 day trip in a few weeks and I plan to test out that rating. It is filled with 900+ down but it is so lightweight I am skeptical. Just something to look at if you are wanting a lighter weight bag option along the same line as the micro.
Cool, thanks for the advice!
