Well, the Gossamer Gear rep agreed the Ranger 35 was too small. Took the Gregory Ranger 40 back to REI to be refitted and it is too small also (load lifters are at zero degrees at max adjustable size).
Now looking at a Gossamer Gear Gorilla 40, with a listed torso size up to 23.25 inches. Pricey at about $200, including a 25% discount! Anybody have experience with that bag?
Many thanks!

I've gear tested for GG and that included the Mariposa and Gorilla. Believe me, the Gorilla is NOT pricey based on the quality of materials, construction, and the amount of time spent developing and tweaking the design. In fact, at that price it is a bargain.
It is a great backpack and if it fits, it will easily carry a Camino sized weight load. I have used the Gorilla to carry 10 days worth of gear and food on wilderness backpacking trips. . A camino load is a piece of cake.
What I would do is to also purchase the newer model of backpad,
called the Air Flow SitLight Camp Seat. Yeah, the product name doesn't match its function as a back pad for a backpack; it is multifunctional in that you can easily and quickly pull it from the back of the pack, and sit on it if taking a break. It is an redesign of the original (which is still included with the backpacks).
I have used the Gossamer Gear backpacks as my personal pack for thousands of miles backpacking. Lately, I am using the Silverback.
Make sure that you have an accurate measure of your spine length and use that to choose a Small or Medium or Large size. Below is a repost of a guideline I wrote for getting a proper fit with a backpack.
Correct Sizing of a Backpack
The size of the pack is determined by the length of your spine, not by how much the pack can carry.
Measuring for a correct fit involves determining your spine's proper length. That measurement is done by using a tape measure and measuring from the protruding 'knob' on the back of your neck which is at the base of the cervical spine, to the place on your spine that is even with the top of the crest of your hips.
- Tilt your head forward and feel for the bony bump where the slope of your shoulders meets your neck. This is your 7th cervical (or C7) vertebra—and the top of your torso length.
- On each side of your body, slide your hands down the rib cage to the top of your hip bones (aka the iliac crest). With index fingers pointing forward and thumbs pointing backward, draw an imaginary line between your thumbs. This spot on your lumbar is the bottom of your torso measurement.
- Stand up straight and measure - or have your friend measure - the distance between the C7 and the imaginary line between your thumbs. That’s your torso length.

Once you have that measurement in inches or centimeters, you can then look at the backpack manufacturer's sizing guide. This guide will be used to match your spine length, to their stated size range.
Sometimes the sizes are expressed as Small to Extra Large. Sometimes that size scale will combine the sizes like: S/M, M/L, L/XL. When the sizes are combined, it usually means that there is a good amount of adjustability to the frame of the pack to customize the fit. That will usually be in the shoulder harness and the hipbelt so that a fine tuned fit can be achieved.
Here is a good video which will help with fitting. Ignore the reference to the manufacturer as the method is pretty universal.
Fitting The Shoulder Harness
First, let me mention that there are differences in the shapes of shoulder straps. The standard shoulder strap shape has been what some manufacturers describe as a "J" shape. This shape tends to fit the chest shape of the male better than the female due to the lesser fullness of the chest. However, even with some men who have bigger chests, the J strap shape can be uncomfortable.
A few manufacturers, ULA and Six Moons Design are the most notable, have developed what is called an "S" shaped strap. This shape has solved many of the fit issues for women, allowing for the straps to properly sit on the shoulders without the uncomfortable compression and chafing due to breasts of larger chests. Here is a link which shows the difference between the two strap shapes:
The shoulder harness should wrap around over your shoulders and sit slightly below the top of the shoulder. The shoulder straps should sit comfortably toward the middle of the shoulder girdle, although that may vary a bit. It should not feel like they are going to slip off your shoulders or sit tight against the base of your neck.
The sternum strap should NOT be required to keep the shoulder straps in place. The sternum strap does connect the shoulder straps, but it is designed to help control where the straps sit on the shoulders with excess pack movement; it is not meant to overcome a poor fit and placement of the shoulder straps.
After fastening the sternum strap in place, pull the adjustment strap until you feel a bit of tension.
The sternum strap on a good pack can adjust up and down on the shoulder straps. The usual placement is somewhere just below the collar bone, but body types and builds will cause a variation of where the sternum strap placement feels best.
Hip Belt Adjustments
For the hip belt, the pad of the belt should sort of 'cradle' the crest of the hip bone: the top of the pad should be slightly above the top of the crest while the bottom of the pad should be slightly below the top. Again, the belt, when it is snugged down, should cradle. The belt should not entirely sit above your hips so that the pad compresses your waist, nor should the entire pad sit below the crest of your hips totally squeezing the hip bones.
There is a lot of misinformation about how a pack's load is distributed between shoulders and hips. It is
NOT true that the waist/hip belt carries the entire load of the pack. It definitely CAN do that, but doing so is undesirable.
There
are reasons which make it necessary to keep the shoulder harness unweighted with the full load weight on the hipbelt. These include damage or injury to the shoulder girdle. There are folks who prefer a total load on the hipbelt even though their shoulder girdle is healthy, but it is a practice which has potential complications associated with it. Even so, it is up to an individual to decide.
If the Hip/waist belt carries the entire weight of the pack
- it means the shoulder harness is unweighted and there can be significant pack movement which, during difficult walking terrain, can create problems with your center of gravity. I have seen people lose their balance and fall as a result.
- It also can result in your core muscles being overworked, stressed and fatigued trying to compensate from that extra movement.
- All of that weight on the pelvis can create significant compression forces by requiring the hipbelt to be over-tightened in order to prevent it from slipping down. This can cause numbness and pain as blood flow and nerve compression is experienced.
- All of the weight on the hipbelt will also place additional strain to the hip sockets and knees.
The load ratio will be about 5 to 15 percent for the shoulders and 85 to 95 percent on the hips. This will allow for the proper engagement of your core muscles to help carry the backpack.
Steps To Adjusting a Backpack Before Walking
I'll add a link to a video (ignore the manufacturer) that shows the best steps to follow when putting on a pack and adjusting it. The basic steps are these:
- Loosen all of the straps on the shoulder harness and hip belt.
- Put on the pack and very slightly tighten the shoulder straps so that the hip belt is slightly below the hips.
- Shrug your shoulders up, and then fasten the waist belt as you are getting it roughly into position.
- Slightly tighten the shoulder straps to assist with the hip belt adjustment.
- Position the hip belt padding to let the padding sit half above and half below the crest of the hips. The padding of the belt should never sit entirely above the hips. The padding should sort of wrap itself over the top of the hip bone and hug the hips.
- Tighten the belt just enough to keep it in position. At this point, nearly 100% of the packs weight is resting on the hips.
- Snug the shoulder straps to take up 5 to 15 percent of the packs weight. You will feel just a slight unloading of the weight off the hips.
- At the top of the shoulder straps and toward the pack, are smaller straps called 'load lifters'. Grasp them and pull to your front. You will feel the weight of the pack lift up slightly and pull more snugly toward your back. This helps with center of gravity and balance. You can experiment with how snug or how loose you want to pull on the straps. A properly adjusted load lifter strap will form a sort of 45 degree angle when viewed from the side.
- On some waist/hip belts there can be a small strap connected to each side of the belt. Again, pulling forward on those straps will bring the bottom of the pack closer to your back, helping with balance as you are walking.
