Flight 30 Ultra Backpack Materials

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.

A bit bouncy, but well built.

I chose this pack because of the capacity and vest-style harness. I tested the fit on a 7 mile trail run with about 20 lbs. The pack bounced a lot, especially with the hip belt tight. The bouncing improved once I loosened the hip belt, but it didn't go away completely. I think I can improve the bouncing further when I dial in the fit a bit better. The pack was built well and was really comfortable when I walked rather than run.

Very impressed!

I used the Flight 30 Ultra with the vest harness to fastpack around the 3 Sisters mountains in OR, 60 miles total + 3 days. I’m 5’7” 125lb and carried approx 18lb. The pack is super stable with no bounce and no chafing anywhere (back, shoulders, hips, chest) while running (jogging). There are so many adjustments that I could get it dialed in for comfort no matter how I had it packed for the day. And the extra side pockets are great for stuffing layers, bear spray and snacks. Everything stayed super secure. My only issue was with the flight vest - it fits a little weird as a woman. It smashed things awkwardly and while it wasn’t super uncomfortable, it wasn’t ideal. I also purchased the S Straps and will be giving those a try, but wanted to use the vest for the overall stability for this trip.
I’d say that the Flight 30 is a workhorse and I was very impressed with its performance. And, I can’t wait to use it again on more fastpack adventures!

Love this Pack!

This pack is perfect for fastpacking. It’s well thought out to be light, plenty of room to pack what you need for multiway packing, great quality, and tough. The vest harness is awesome with deep pockets to hold soft water bottles and snacks. It holds the pack in place as you run. It’s great in every way!

Very comfortable

Very comfortable I like how it distributes the weight to my chest. Good pack wish it came in some bright robic or silnylon colors like orange or red.I didn’t go with the ultra I don’t really need the waterproofing since I usually use a poncho.

Nice pack!

Bought the pack with the flight vest harness to get more volume than my well-worn Osprey Talon could provide on long all-weather day hikes. I have carried it approximately 100 miles so far on a mix of New England and Colorado trails with weights between 15-20 lb., and once I got the flight vest dialed in it has been great. Comfortable, reasonably water-resistant, lots of room in the exterior pockets, the load feels like less weight than you are carrying, and the vest harness has plenty of options for anything you need to access fast. Plus it's a good-looking piece of gear. Worth serious consideration for anyone looking for that sweet spot between a typical daypack and a full-on backpack.
Rating a 4 instead of 5 due to concern about long-term durability. I have already put a few small impact holes in one of the outside pockets from rock scrambles, so not sure how it will hold up over time where I typically hike.
