Direct Answer
The best hiking backpack fit for wide shoulders comes from a pack with a wider yoke — where the shoulder straps anchor to the pack body — plus load-lifter straps set at a wider angle, both of which let the straps sit flat across the shoulder instead of pinching in toward the neck.

In plain English
Picture a backpack's two shoulder straps as the arms of a coat hanger. If the hanger is too narrow for the coat, the shoulders bunch and pull inward. Straps work the same way: if they start too close together at the top of the pack, they angle in toward your neck and press on the muscle there instead of lying flat.
Fixing this is partly about the pack and partly about adjustment. Some packs let you move where the straps start, and some offer straps in different curves for different shoulder shapes. Small straps matter too. The short straps from the top of your shoulders to the pack, called load lifters, and the strap across your chest can both pull the shoulder straps inward if they're too tight. Loosen those first before deciding the pack is wrong for you.
The most reliable fix for wide shoulders is a pack with a wider yoke — the point where the shoulder straps anchor to the pack body — combined with load-lifter straps set at a wider angle, since these two features determine whether the straps sit flat across the shoulder or pinch inward toward the neck.
What causes the pinching in the first place?
Shoulder straps pinch when their anchor points sit closer together than the wearer's actual shoulder width, forcing the strap to angle inward across the top of the shoulder before running back out to the arm. This is a shoulder-width problem, separate from torso-length sizing — a pack correctly sized by the C7-vertebra-to-iliac-crest torso measurement can still pinch if the yoke itself is narrow.

Fixing fit on a pack you already own
Loosen the load-lifter straps first, since over-tightened load lifters pull the whole harness inward and are a common, easily-fixed cause of shoulder pinching. Next check the sternum strap — if it sits too low or too tight, it also draws the shoulder straps together across the chest. These two adjustments resolve mild pinching on many packs; persistent digging or chafing after both adjustments usually points to a yoke that's simply too narrow for the wearer, which adjustment alone can't fix.
Strap shape versus yoke width
Width isn't the only variable; the curve of the strap matters too. ULA says S-shaped straps suit standard or sloping shoulders while J-straps suit flat or square shoulders,1 and it offers both options on packs such as the Circuit.2 Broad, square shoulders often sit better in a straighter J-strap that runs out toward the arm before turning down.
Women's harnesses can work against wide shoulders. Deuter's women's SL packs use narrower S-shaped shoulder straps,3 which suit many women but may pinch a woman with broad shoulders; a unisex harness in the right torso size can be the better fit. Mystery Ranch's adjustable yoke is telescoped until the shoulder-strap seam lines up with the top of the shoulder blade,4 one example of a harness that lets you move the anchor point. Kelty's fit check is a useful test for any pack: the straps should run over the shoulders and only just begin to angle down toward the pack.5
Why strap pressure hurts, and how much the hips can take
A study of load carriage found the hip region tolerates pack pressure significantly better than the shoulder region, that static strap force was a significant predictor of discomfort, and the authors recommended shifting load from shoulders to hips wherever possible.6 Deuter's fitting advice matches: shoulder straps shouldn't be over-tightened because the waist belt should carry the main load.7 Gossamer Gear adds that straps set too high pinch the neck, while straps set too low reduce weight transfer to the hip belt.8
How much the hipbelt actually takes is contested. Big Agnes aims for about 80% on the hips,9 Alpkit says 60 to 80%,10 and US Army doctrine says that with a frame and hip belt, about 30% sits on the hips and lower back and 70% on the shoulders.11 Whichever figure is closer for you, the shoulders always carry some load, which is why strap geometry matters for broad-shouldered hikers.
Load lifters and sternum strap by the numbers
The page recommends a wider load-lifter angle, closer to 45 degrees. Brand guidance spans a range: Big Agnes says 45 degrees,12 Deuter says 30 to 45 degrees,7 and Alpkit says 25 to 45 degrees from horizontal.10 If lifters feel like they are dragging the straps toward your neck, ease them until the angle opens up.
Sternum strap height also varies by source: Big Agnes places it below the collarbone, lying flat with moderate tension,12 while Alpkit puts it about an inch below.10 Deuter sets it only after back length is correct.7 On a wide chest, moderate tension matters more than exact height, since a tight chest strap is one of the fastest ways to pull straps inward.
