Ordered this for a future 1 month- 1 bag, cold weather international adventure. Today-the half-cube arrived, the envelope weighed more than the bag...shoot...the tag and cellophane weighed more-so, yeah, I'm SUPER excited! I have jeans (stretchy...but I'm no pixie), and a women's down vest, and a thermal base layer, and 2 poorly-packed-second thought pairs of panties fit in one of these little guys...with ROOM to SPARE... I could easily zip it. I bet a second base layer top or leggings could easily fit- perhaps a pair of socks too if I packed properly. A plus...it was REALLY easy to close...sorry ZipLoc. I think packing outfits in these will be the best way to go.  I ordered a second (and I'm going to try compression cubes from Eagle Creek).
PS: The tag shows an undershirt and a pair of shorts....pfffft
