If this bag is reversibla and you can unzip it all the way down one side and all the way down the bottom to use as a blanket, what difference does it make which side the zipper is on? With the baffle side out, the zipper will be on one side. By reversing the bag and having the smooth side out the zipper will be on the other side of the bag. Is my logic correct on this?
Yes, this bag unzips down one side and the bottom. The zipper disconnects and allows you to open the bag completely. However, the bag is not insulated on the bottom. So half of your blanket would be the insulated quilted side you see in the picture, and the other half would be fleece. It actually has has three levels of insulation. The item picture shows the 2nd level of insulation. you can turn it inside out when it gets colder, or turn it over (laying on the baffled half) when it gets warm. This is a great bag, but it is intended to be used as a liner and used with another bag and sleeping pad.
Personally, I use this bag alone more often than not. It packs down very small (6.5"x14") and comes with a stuff sack that's lined with fleece that makes a good pillow.
You're right about the zipper. On the warmest setting, the zipper is on one side, and changes when you turn it inside out.
YES! Logic is correct. This is my favorite summer sleeping bag.
yes, that's correct. however, think of the zipper being on the side that you *would use most frequently. if you have do a ton of winter camping/hiking and are using it as a liner, the zipper would be on the one side (to pair with your current bag). if you do a ton of summer camping/hiking the zipper would be on the opposite side as the cold-weather configuration (because you essentially turn the bag inside out to move the baffles facing outward or inward).
all-in-all it doesn't really matter what side the zipper is actually on in part because in one configuration or the other, the zipper may be on the opposite side (if inside out). but, also, seriously: it's just a zipper... it's not the end of the world if you've got to roll over twice to unzip yourself from two bags.
speaking from my own experience using this bag, it's a great piece of gear to have because you can continue to use it during all seasons, as a liner for cold-weather or standalone bag for warm-weather. depending on the length, you're looking at 750g-800g or 1.5-2lbs not a whole lot. it packs down to about the size of a summer weight down bag. (2-3 nalgenes). Another feature that I really liked is the stuff-sack which can be used as a pillow if you fill it with your sweatshirt or down jacket. the whole thing is pretty well conceived and constructed. if you take care of your gear, this will last a long time.
summed up: versatile, lightweight, packs small, *included* pillow, zipper side doesn't really matter.
