How to Choose a Pack Size

Your 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.
    • Extra Small (< 15" torso)
    • Small (15.0” - 17.0” torso)
    • Medium (17.0” - 19.0” torso)
    • Large (19.0” - 21.0” torso)
    • Tall (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.

How to Choose a Pack Size

The Southwest is a versatile backpack that is easy to adapt to a variety of backcountry activities, from trail hiking to exploring rugged off-trail environments. While the main body of the pack is built the same way as the Windrider and Junction, the Southwest features solid-fabric exterior pockets for added protection in abrasive, rocky terrain. Using lightweight, waterproof Dyneema® composite fabric and a proven, durable design, the Southwest is a lightweight and comfortable pack that offers premium performance wherever you’re headed.

KEY FEATURES:
  • Durable solid-fabric exterior pockets protect gear and hide contents, ensuring your items stay safe and out of sight during your adventure.
  • Side and over-the-top compression straps securely hold external gear, preventing shifting and keeping your load stable, no matter the terrain.
  • Hydroport and internal mesh sleeve provide easy access to water, making it simple to stay hydrated on the go without slowing down.

Looking forward to using it!

Read all the reviews and am looking forward to using it on a couple of trips this summer! I like the feel but will need to comment later on how it is after carrying around weight in it for an extended period of time. Otherwise, I am excited to use it.
