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.

UL Fastpacking / Thru Hiking / Backpacking

KEY FEATURES:

    Not perfect but very very good

    I got this pack a few months ago and have been using it 3-5 times a week for run commuting, so my review is based on that use, which I think is relatively translatable to a fastpacking use case. I had previously used the Salomon XA25 for this purpose. That's a solid bag, but the Aero is an improvement, and I look forward to putting in some real fastpacking miles with it this summer.

    On run commutes, I typically load it up such that total weight is 7-9 pounds. It carries the weight incredibly well. There is some bounce while running, but I think that is somewhat unavoidable, and the smooth dyneema back panel doesn't chafe, so slight bouncing hasn't bothered me. The main latch that secures the roll top combined with the two side latches create a compact feeling, like all of the pack contents are very secure. The vest straps are ridiculously comfortable. Overall, the materials, construction, and durability are stout. Have run home in the rain several times, and inner contents remain dry. The bottom pocket is super handy for quick storage, and side pockets are accessible and secure bottles well. And heck, have even gotten a few compliments on the style factor as well.

    Two downsides: for a pack of this price, it's kind of silly that the one single zippered pocket in the entire pack -- the one supposedly designed for phones on the vest harness -- does not fit a normal sized iPhone. I have an iPhone 15 with a slim case and it's not even close to fitting. I mean, c'mon. Related,…

    My favorite pack!!!

    I used the Aero 28 for my 208 mile run on the entire state of New Jersey. I ran from the lowest point the Cape May Lighthouse, to the highest point the Hugh Point Monument to raise funds for the Forum School in Waldwick NJ. This was a solo self supported effort and the first 3 days were in poring rain. I paired the pack with the Hyperlite Vice Versa with the waist belt ran through it and it was a great combo. The pockets in the vest straps are a tight fit for my phone and extras especially with flasks in the pockets, so the Bice Versa fanny pack was the perfect addition to have my phone, wallet and snacks readily available. The pack is functional durable and dependable, paired with Hyperlite stuff sacks I was able to keep all my gear completely dry from the constant rain I was in. The weight distribution of the pack is really nice, it was an insane amount of storage without being big and bulky. I love this pack and it's my go to for all my adventures bow. I highly recommend this pack. The padded supportive back idle really nice but the airflow is limited and you will definitely sweat in warmer weather, but it didn't bother me.

    Just what I wanted for fastpacking

    I am extremely pleased with this new pack. Great materials, very comfortable, big enough but not too big. Front flask pockets are deep enough to hold my 1/2 liter flasks which was a big deficiency on my “old” pack from another company. Lighter weight will also be greatly appreciated in the (literal) long run.

    Portland Maine Run Commuter.

    I purchased this pack as a late Christmas present for myself, and I am quite pleased with it. I primarily use it for run commuting to work and find that it rides well and is very comfortable, even when packed with my heavier work clothes, lunch, and winter jacket. The vest-style pack has become my go-to option, and I am thrilled to see that Hyperlight has made this pack. Super excited to get out on the trials for some fast packing in the warmer months.

    Fast Pack for the win

    As an older hiker I'm always looking for ways to be more comfortable and lighten the load. We just finished the Jacinto hike Cactus to Clouds and this pack made my whole hike. The fast access to snacks and the features of this bag made my day.

    Thanks for making a great pack.
