For best fit, you will need your torso length, hip and waist measurements. 

Torso length:

1. Start at the C7 vertebra at the base of your neck. The best way to find this is to bend your neck and feel the first bump along the base of your neck. This bump is where you will want to start your measurement. 

2. Next, you'll want to find the midpoint between your iliac crest. To find your iliac crest, cup your hip bones on both sides and find the center point on your spine. This midpoint is where your thumbs should be pointing. 

3. Finally, measure from the C7 vertebra to your iliac crest. From there, you'll have your torso measurement. 

Torso length 40–45 cm | size S | usually for heights up to 168 cm

Torso length 45–51 cm | size M | usually for heights 165–180 cm

Torso length 51–56 cm | size L | usually for heights 178+ cm

Hipbelt Sizing

Hip Measurement: 

1. You will want to find your iliac crest again by cupping your hip bones on both sides.

2. Then, wrap a soft measuring tape or string around the top of your iliac crest. This will tell you your hip measurement. 

PVT Belt Sizing (Hip Measurement)
S/M Curved Belt | 28.5"-56" (72.4-142.2 cm)
M/L Curved Belt | 32.5"-60" (85.5-152.4 cm)
S Straight Belt | 26"-53.5" (66-135.9 cm)
M Straight Belt | 30"-57.5" (76.2-146 cm)
L Straight Belt | 34"-61.5" (86.3-156.2 cm)

Waist Measurement:

1. Using the same soft measuring tape or string, find the smallest part of your midsection—typically, this is 1-2 inches above your belly button. 

2. Measure around that area for your waist measurement. 

Waist to Hip Ratio:
Calculate your WHR by dividing your waist measurement by your hip measurement. 

If it is 0.85 or lower, you will likely need a curved hipbelt. If it is higher than 0.85, you will likely need a straight hipbelt. If you're unsure which hipbelt shape will fit best, we recommend purchasing both to dial in the fit. This is because everyone's anatomy is different. 

We all have unique body types, so two people of the same height may be better suited to two different sizes. That's why it's important to measure the key dimensions and choose according to your own measurements.

Torso length – important for backpack size

The upper point of the torso length is the C7 vertebra. You can find it by bending your head forward and feeling for the most prominent bone bump on the back of your neck.
The lower point is located on the spine between the upper edges of the hip bones. You can find it by feeling the upper edges of the hip bones with your index fingers, placing your palms on your hips, and pointing your thumbs toward your spine. The point where your palms meet is the lower point of your torso length. Simply measure the distance on the spine between these points; it is best to ask someone to measure the distance for you. You can use a soft tape measure or a piece of string, which you can then measure.

This fastpack is designed to be worn higher and tighter than our original Kumo. For this reason, the back length for S/M is 40.6 cm and 45.7 cm for M/L. Please keep this in mind when selecting your size.
