Our men’s/unisex cut bags have the zipper on the left side, and our women’s cut bags have the zipper on the right. For a bag like the Flicker, the zipper is on whichever side you want it to be on -- or even in the middle! Other hoodless bags like the Condor or the Penguin can be used with the zipper on either the left or right side; if you’d like to zip on an optional hood, it can be zipped to the bottom of the bag in either configuration.
