PACK SIZING GUIDE

S Straps vs J Straps? Torso size? Follow our helpful guide to get the best fit.

S v J Strap Comparison


1. TORSO FIT

  • Standing upright, tilt your chin to your chest.
  • Locate your C7 Vertabra—the large lump at the base of your neck.
  • With flexible tape, measure down the length and natural curvature of your spine to your iliac crest/ the top of your hipbone.
  • This measurement in inches is your torso length.

TIP: If you're between 2 sizes, order the smaller size. Still not sure? Contact us.



2. TORSO CHART

We've found most people in these height ranges fall into these torso/pack sizes. That being said, it is always best to measure your torso using the guide above.

If you're between sizes and you are getting a FRAMED pack, we recommend you size DOWN!

If you're between sizes and you are getting a FRAMELESS pack, we recommend you size UP!

If you have questions, or your torso size doesn’t seem to make sense for your height, please contact us.



3. HIPBELT FIT

Use the following method to determine your hipbelt inches, then head to Step 4 to see the hipbelt size you need.

MEN

Pant Waist Size + 2".

WOMEN

CURVY HIPS: Smallest part of your waist + 5".
STRAIGHT HIPS: Smallest part of your waist + 3".

KIDS

Smallest Part of waist + 2".



4. HIPBELT SIZE CHART

Find the hipbelt measurement you calculated in Step 3 on the chart. That will be your hipbelt size.

TIP: If you are on the outer edge of a size, order the larger size. [ Ex: If you are 38", you will notice 38" is the last number of the Medium Hipbelt and the first number of the Large Hipbelt. You would want to order a Large.]



5. SHOULDER STRAPS

The downward slope of your shoulder profile usually determines strap preference. You can assess your shoulder slope profile by looking in a mirror or having a friend look at the angle of your shoulder from the base of your neck to your shoulder point. 

If there is relatively little or no downward slope, you have what is referred to as flat or squared shoulders.

If there is a noticeable downward slope, you have what is referred to as standard or sloping shoulders.

J STRAPS

J-straps are the traditional straight straps. They are best suited for people with flat or square shoulders, as their flat shape provides better surface contact and less rub.

S STRAPS

S-straps contour body curves. They are best suited for people with standard or sloping shoulders, as their contoured shape better hugs your shoulder slope.

TIP: If you have a short torso but a larger upper body, you may need a slightly longer strap. If you are very large in the upper body, you might need XL shoulder straps. Contact us, and we would be happy to make these customizations so your pack is comfortable and fits well.
