Pack Organization

The Flight Ultra is a 30L daypack – or multi-day pack if you’re into going super ultralight. Unlike the Flight UL, the Flight Ultra has a new large capacity bottom pocket made of woven nylon, making it even easier to stash and access items on the go efficient, small volume pack.

There are also 3 pockets on each side of the vest, large stretch pockets on both sides on the front of the pack, daisy chain webbing, and a bungee stasher.

Everything you need is within easy reach. With so much convenient storage, you won’t have to shed your pack until you’re ready to make camp.


The Flight Ultra comes in two fabric options - Robic™ nylon or our new EPX200 fabric. EPX200 is a robust fabric by Challenge Sailcloth. It is made using 3 layers of 210 denier fabric making it not only waterproof but very abrasion-resistant. While EPX200 is waterproof the packs themselves are not water tight. We recommend using a 50L Pack Liner.

Super comfortable

A mark of an excellent pack is not knowing that it is there. After making a number of adjustments, on my most recent runs, it was almost as if the pack was not there.

Wendy Newman
Almost perfect pack

I tried a lot of packs before I finally landed on this pack! Being 5’1” and 101 pounds it was hard to find a pack that would fit. With the adjustment of the length and the options for size of the shoulder harness and hip belt it fits me perfectly! I can attest after ordering and returning at least 5 packs this pack has more adjustments too make it the most comfortable pack I tried. I love the shoulder stay adjustment and the hip belt adjustments. This pack also fit water bottles in the front very easily and trust me with other packs it was a fight. The zipper pockets in the front fit my iPhone 11 Pro. My only 2 things that kept me from giving it 5 stars is the additional pockets on the front have a weird slant to them and I would be worried about losing stuff out of them. I also wish they had a big stash pocket on the front of the pack, but it does have bungee attachment for stuff and I’m sure if I was carrying more camping gear I would appreciate it.

Impressive Design, Features, Comfort

I just took my new Flight 30 Ultra backpack on its first fastpacking / running trip, and I’m very impressed by all of its features and overall design.

I found it to be the most comfortable pack I’ve had. The suspension system of straps and their adjustments is great, and allows you to really dial in your fit. I also really appreciated the layout and accessibility of all the pockets and external features.

This pack has quickly become one of my favorite pieces of gear. My only disappointment was finding the pack to perhaps not be as abrasion resistant as expected, given that the description highlights the durability of the EPX200. A small tear in the EPX200 started showing, likely from being leaned up against a rock while the pack was not on my back, on only its first trip. Granted, our the granite can be quite coarse and sharp at times here in the High Sierra, but I still would’ve liked it to perform better in that regard, since otherwise I do really love the pack so much.

It's great

Not using this for running, just regular hiking. This is the only top-loading ultralight pack in this size category that had a substantial waistbelt that can support the whole weight of the load. I have it set up at 20# with the whole weight on my hips, and the S shoulder straps just tight enough to keep it from flopping around. I was first wondering if the shoulder straps would be weak at the attachment point because of the velcro, but it feels very solid. When I lift the pack, I grab it by the shoulder straps and it hasn't budged. Comfortable to carry and the pack seems sturdy. Really like the capacity of the side pockets, in one I have a 64 oz stainless steel water bottle, in the other a Grayl Geopress and a 33 oz Smartwater bottle. I also like how narrow it is, even with my large protrusions from the side pockets, it still doesn't stick out past my body if I need to squeeze through a narrow area. 6'3", 210#.

Well made, comfortable fit.

I bought a competitors pack at the same time to compare and six moons was far more comfortable. It is well built and has lots of useful features.
