Gossamer Gear Vanish 38L Duffel
To find the best fit for the PVT packs, you will need your torso length, hip and waist measurements. Below are recommendations on how to measure each of these.
Torso length:
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.
Next, you'll want to find the midpoint between your iliac crest. To find your iliac crest, cup your hipbones on both sides and find the center point on your spine. This midpoint is where your thumbs should be pointing.
Finally, you'll need help measuring from the C7 vertebra to your iliac crest. From there, you'll have your torso measurement.

Small: 16" - 18" (40.6-45.7cm)
Medium: 18" - 20" (45.7-50.8cm)
Large: 20" - 22" (50.8-55.9cm)
If you're in between sizes, you can:
+ size down for more of a shoulder wrap and higher hip belt
+ size up for a lower hip belt fit
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)
Hip Measurement:
You will want to find your iliac crest again by cupping your hipbones on both sides. Then, wrap a soft measuring tape or string around the top of your iliac crest. This will tell you your hip measurement.
Waist Measurement:
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—and 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.
