How to Choose a Pack Size

How to Choose a Pack SizeYour torso length, not your height, determines your pack size. We recommend the following to determine yours:

  1. Tilt your head slightly forward to locate the bony bump at the base of your neck. (This is your 7th cervical (or C7) vertebra).
  2. Using a flexible tape measure, have someone measure starting at that spot and running down along the curve of your spine.
  3. Place your hands on your hips so you can feel your iliac crest, which serves as the “shelf” of your pelvic girdle. (It’s the first hard thing you feel when you run your fingers down from the sides of your ribcage.) Position your hands so your thumbs are reaching behind you.
  4. Have your friend finish measuring at the point where the tape crosses an imaginary line drawn between your thumbs. This distance is your torso length.
    • Small (15.0” - 17.0” torso)
    • Medium (17.0” - 19.0” torso)
    • Large (19.0” - 21.0” torso)
  5. If your measurement falls right in between sizes (for example, if you have a 17.0” torso, so you are right on the line between a Small and a Medium), we suggest you choose the larger torso size.

Stay comfortable and move freely on the trail with the Aero 28. Designed with a close-to-body vest-style harness, it gives you easy access to food, water, and gear—so you can keep going without stopping. Whether you're pushing for a fastest known time or just racing the sunset, this pack has your back.

DESIGNED FOR:

UL Fastpacking / Thru Hiking / Backpacking

KEY FEATURES:
  • Vest-style shoulder straps keep hydration and calories within reach, offering easy access during active pursuits.
  • The bottom pocket, front stretch mesh pocket, and two oversized side pockets provide quick and easy access to gear.
  • The roll-top pack closure with a single top compression strap ensures secure packing and easy volume adjustments.

Fit: Take into account your typical pack size and shirt size, as well as your body type and chest measurements. With the running vest design and the likelihood of some stretch, opting for a smaller size may provide a better fit for those with a slimmer build.

  Chest Size (circumference)
 Torso Length: Under 40" Over 40"
 S (15"-17") S M
 M (17"-19") M L

    Did well on the TMB

    I bought this pack to hike the Tour du Mont Blanc with. I was not nice to it, and it was durable. Nothing broke or tore. As others have said, the pockets suck. I realize it is meant to be a fast pack and the front pockets are really just for your energy of choice. Don’t care. The pockets suck. Pack feels good. Obviously I’m packing light to begin with, but I did not miss a hip belt. I removed the strap it comes with. Didn’t need it. Back never felt sore. If I could change anything it would be good chest pockets and maybe some slight padding on the shoulder straps. There were days I brought extra water, and my traps could feel it. 9.99/10 would hike the TMB again with it.

    Great Fastpack

    Took the Aero 28 on a two day trip circumnavigating Mount Hood. As a runner, I’m used to traveling much lighter, and wanted something similar to a vest, but with the ability to handle multiday adventures. This pack handled my set up with space to spare, and I’m very happy with how stable it was running. I’m looking forward to many more adventures with the Aero 28.

    Aero 28 - Excellent Running Backpack

    Just completed my 2nd 250k multiday stage race with this pack. I have now used this pack for around 2 years almost every day. This pack is robust, lightweight and extremely comfortable. The bottom strap is on its last legs, but I have been pushing the pack to its limit, carrying ~10-12kg in training.

    Although you can find bags that are lighter weight, they are not as comfortable or durable.

    Photos are from Gobi March 250k (racing the planet) - Managed to have the lightest pack weighing in at 6.1kg. Won 3 of the 6 stages, placed 2nd overall, 1st male. The pack was a large part of my success. Love it!

    Aero 28

    Great pack, just as I was hoping it would be. Only wish it had a compatible padded hip belt to buy. Other than that it’s excellent.

    Fantastic multiday fastpack

    Out of the 6 packs I have this is by far my favorite and the one I reach for every time, the comfort, weight, zero bounce, ability to run, ability to rock scramble makes this pack a solid choice.

    Will be selling 5 packs soon.
