The Gila 3500 2.0 is built for fast overnights, day hikes, or extended trips for the minimalist who values performance. Designed to carry 30–50 lbs with ease and capable of handling 200+ lbs, this updated version features UltraGrid™ in Castlerock—a limited-edition fabric we’re discontinuing after this run, so get it while it lasts. The Gila 2.0 upgrades include an UltraStretch™ front pocket, forward-pull hip-belt closure, stretch water bottle pockets, and a streamlined design. The removable Top Lid adds organization (or sheds weight when needed). Renowned in the lightweight world for its durability and heavy-load comfort, the Gila pays homage to its namesake—the Gila Wilderness, America’s first protected wilderness (1924)—with a build meant for rugged solitude.
Like all our gear, it’s handcrafted in-house with premium materials and backed by our lifetime warranty against manufacturing defects. Because this is a limited run, no returns after 30 days—once it's gone, it's gone for good- don't miss out

Our frame will support over 300 lbs in vertical load. YOUR max load will be determined by your body, not by the pack.

Fitting:
A good fit requires several things:
After fitting the pack to your body, you can tune comfort with three hard breaks. These adjustments drastically change the feel of the pack and users typically have a strong preference for each of these.
This is good because it speeds the adjustment process....if you don't like the way the pack feels change one of these and it will feel very different.
These cause hard breaks in the feel of the pack:
Achieving a good fit starts with the correct torso length. To read in-depth about torso length, adjustable frame height, and load ranges, see Which Frame Height is Right for Me?
Torso length is the distance from C7 (the prominent vertebrae at the base of your neck) down the spine to an imaginary line drawn connecting the points of the hips (iliac crests). Common measurements for a 6' tall male would be 17 to 19", while a 5'5" female may be 15 to 16", though these measurements vary widely based on body composition.
Match your torso length with the correct frame height for your expected load ranges. One advantage of our Field Adjustable Frame Height is that you can shrink the pack down for day loads and expand the height for heavy loads on the fly.
Frame height preferences vary person to person, so be sure to experiment and see what YOU prefer.
Shorter frames give less shoulder lift (upward angle to shoulder strap, lifting the harness), but they give you more freedom of movement to look sharply upslope, and snag less on overhanging branches.
Taller frames give more shoulder lift, but also can limit head movement and snag more.
In general users often prefer shorter frames for lighter loads and taller frames for heavier loads, but preferences vary.
People wear hipbelts high and low. This can change their effective torso height and throw off the guidance above. So using the frame height relative to the ear can be a better guideline in some cases.
The padded portion of the hipbelt should wrap around the front of your hipbones, yet not so far that you run out of webbing adjustment. Consider seasonal use and clothing worn when selecting your size.
Most users want to center the hipbelt over the points of the hips. This is an excellent starting point for belt position on the body.
Hipbelts are connected to the frame with a grommet and screw. The Hipbelt has three grommets - a high, medium, and low.
Many users prefer the highest position to raise the frame up relative to the belt, but again preferences are all over the board here. If the belt isn’t comfortable try a different position.
Lumbar Pad vs No Lumbar Pad - you will probably strongly prefer one or the other. Telephone pole builds (flat back, straight up and down) often prefer no lumbar pad, while curvy or beefy builds often prefer the lumbar pad.
Captured vs Floating Belt - Captured can only be done WITH a lumbar pad. Floating can be done WITH or WITHOUT a lumbar pad. Less significant than the lumbar pad in changing the feel of the pack, users still usually prefer one or the other. Captured keeps the hipbelt upright and can help prevent the 3D mesh face from collecting snow or pine needles.
Floating vs. Captured Harness - the straps that adjust torso height have holdfasts on the suspension that secure the harness. Two adjustments can be made to free the harness.
To free the harness:
These two changes move you from a captured / stabilized harness to a floating harness. People who prefer a floating harness often roll their shoulders forward when hiking, and the extra give in the harness system conforms to their upper back better.
One final tip - Users who prefer no lumbar pad often prefer a floating harness.
