  • PVT Frame System

    Our Patent Pending PVT Frame system is designed to maximize your comfort on trail. The closed-shape aluminum frame provides rigidity and strength that matches your back's contour. It slips in the pocket of a pivot belt that fits you like a glove. Together, the system allows your pack to move with your natural gait.

  • Alternative Belt Options

    Available in multiple sizes, as well as straight and curved fits, this hipbelt hugs your body for optimum weight transfer. Say hello to less chafing and more comfort.

  • Redesigned Load Lifters

    The Gorilla load lifters have been redesigned alongside our new frame for an improved performance and better carry.

Gear Notes

Megaversatile, ultralight, and insanely durable. This pack is for plan-ahead thru-hikers and minimalist warriors. For being so light, this animal comes loaded with features.

Enjoy our signature PVT Frame+Belt: an aluminum, closed-shape frame and pivoting hipbelt that allow your pack to move with your natural gait for maximum comfort. The Gorilla's S-curve harness and load lifters carry your haul with even distribution. You also get ample external pockets and a quick-access, fold-over lid to hold as many bananas as you see fit.

**Our Small Gorilla comes with a S/M Curved Belt. Our Medium and Large Gorilla comes with a Medium Straight Belt. The process for receiving another belt is to add an additional hipbelt to your order, swap it out at home, and then return the original belt for a $25 refund.

Sizing & Fit

To find the best fit for our PVT packs, you will need your torso length, hip and waist measurements. Below we will give you 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. 

Torso Fit Illustration
Small: 16" - 18" 
Medium: 18" - 20" 
Large: 20" - 22" 
If you're in between sizes, you can: 
    + size down for more of a shoulder wrap and higher hipbelt 
    + size up for a lower hipbelt 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.
