It looks incredible <| sep |> I use a Marmot Kompressor because I ' m too cheap to buy the cuben fiber to build my own pack right now . I have a trash compactor bag that I used to line the inside for extra water protection . When I pack I use my air mattresstentbedroll as a liner around the outside and then pack the rest of my gear inside of the little tube it creates in order to help add rigidity and form to the pack without having to actually add any dead weight supports . Still leaves me room for a cook kit and other gear and makes sure the load doesn ' t shift . Oh , it was also very cheap . like I got mine for $ 40 dollars cheap . Build quality is pretty good , although it ' s definitely an ultralight pack because you couldn ' t load it up with anything too heavy . The only major drawback that I ' m wanting to fix is a lack of shoulder pads . If you have heavier gear then I ' m sure it would suck for longer trips . Currently I ' m planning to make a set of sleeves for the shoulders and I can then stuff them with pairs of socks . dual purpose ! DEdit Just realized you ' re looking for a 40 L sized pack . This is definitely not what you ' d want . Sorry !
