  • Starting with a Vest Harness that offers excellent load carrying capacity on its own. The vest is attached to the pack in two places and, when tightened, is designed to pull the pack body up and into your back putting the load onto the vest system. When combined with the Hip Belt the pack will hold firmly to your body and keep the pack from moving around while hiking. The Hip belt articulation is accentuated by our unique closure. Each of our straps are independent and terminate at the buckle. This allows you to set different levels of tension between the top and bottom of the hip belt. Straps that don't have two adjustment points on each side and simply loop between the top and bottom of the belt will reset to a central position as you walk.

    A Delrin hoop stay inside the pack bag, provides enough support to enable load transfer with minimum weight. The bottom of the stay is directed back to a junction to the center of the pack. This junction provides a direct connection between the stay and the hip belt. Typically with ultralight packs, the stays and hip belt are separated by several inches of fabric. The result is that when weight is applied to the stay, the pack sags.

    With the Flight 40, all of the downward force from the stay is transferred directly to the hip belt. With the hip belt and stay, the load radiates out over a large surface area eliminating pressure points.

    A great pack for the price!

    While others were fiddling with their straps, shifting weight from one side to the other mid trail, my pack stayed true and comfortable throughout the entire trek thru a small section of the PCT (Echo Lakes to Lake Tamarack). This pack is by far one of my most comfortable and most affordable. 40L was enough room for this single backpacker with a few luxuries in the side pockets. The added pocket for a small water bottle attached to the shoulder strap on either side was a definite plus that other backpackers were envious of. JMT worthy? we shall see. Thank you, SIX MOONS!

    absolutely great Hiking 10 miles in instead of taking a break I pushed another 10 miles the harness setup is better than I thought the pockets will hold a 16.9fl smart water bottle and the others held plenty of snacks goodbye osprey

    Overall very good, but not quite perfect

    I have a number of high quality race and fastpacking vest and back packs, and have come to learn that when I'm deep in the back country areas, I need to be able to 100% trust my gear is up to the task. Equipment failure 100kms from no where can turn a manageable run into a nightmare. Things I really like about the pack. - Feels very comfortable with the vest harness - The belt provides loads of support and together with the harness I have minimal movement of the pack (trial run with about 7-9kg in the pack) - I like lots of pockets, and they appear to be relatively easy to access (my shoulders aren't very flexible) - The pack just feels rock solid like it's not going to fail me. Even with that weight in the pack the straps didn't feel like they were at their limit - Clips and buckles are all solid and felt secure Things I didn't like - The zip pocket only just fit my Samsung phone. It took a bit of a squeeze to get it in, and as the newer phones come out I'm sure that pocket will start to get too small - Neither my Salomon or UD bottles fit the hydration pockets. I've order new bottles that will hopefully fit, but I'm not 100% convince yet that they will ever fit a 500ml bottle as the pocket is very short. - The included hydration sleeve is on the small side, probably only fit a 2L bladder. Water supply in Australia is sparse, and I'll often have to carry up to 2 days worth of water. - Lots of straps flapping about the place. A few extra loops to hold the excess strap length would go a long way - I would love to see dedicate pole carrying straps. Ideally ones I can reach without having to take the pack on and off. - Ordering process is confusing. Ticks for the fast response to emails, but there are many ways you can make it more obvious exactly what I'm ordering (especially if you won't take returns) This might sound very demanding and picky, but when I'm paying premium money for a premium product I expect it to be perfect. I could have spent half the money for something half perfect, but I'm pursuing this product because I want something perfect. And it nearly is perfect. In summary, no it is not quite perfect, but yes I am happy with it, and yes I would recommend it to someone else to buy.

    Fantastic Bag

    I've got well over 100 running miles in this bag including a 35 mile fastpack trip in Los Padres NF. I just finished a two night backpacking trip in Lassen with it. All I can say is wow. bought this bag because I was interested in fastpacking, and it has usurped my Osprey UL bag as my go-to for 1-2 night backpacking trips as well. the roll top allows the bag to shrink to the size of a day pack for shorter adventures. It truly is a do-it-all bag. The UL vest and hip system is very comfortable, especially while running. The first time I ran in this bag I threw 15 pounds in it and in a few miles I had completely adjusted to the weight. Once you're under way in this system you don't feel the weight anywhere, you just go slower and get tired quicker. I use the bag several times a week on runs in the East bay, with anywhere from 10-20 lbs in it, I love using it on runs with people who are a bit slower as it levels the playing field between us. I normally fill it with a gallon milk jug of water wrapped in a heavy winter jacket. The bag feels extremely durable. it certainly hasn't experienced any damage from the trips Ive been on in it, crashing down overgrown trails and skimming against rock walls. The fused strip beneath the armpits that the vest harness strap runs through makes me nervous but it hasnt suffered any damage or stretching yet. My only critique is a wish: that the chest sleeves in the vest harness were deep enough to accomodate the hydrapak breast bottles used in salomon hydration vests. Maybe consider in future iterations of the bag enlarging the breast sleeves so that popular softbottles will fit. I have no problem running my 3L osprey hydration pack in the included sleeve in the bag. six moon hit it out of the park with this one. 5/5
