I have a ~22 inch torso. I bought the osprey poco plus child carrier which says it supports 22 inch torsos. I went a couple three hour hikes this weekend and my shoulders were done at the end of each. this isn’t normal, right? I am thinking of trying another carrier, but i am worried there are no child carriers for tall people.
Want to second two things here: Extending the back and tightening the waistband.
I use an osprey day pack when I’m solo day hiking. For the first few times, I didn’t extend the back, and I really felt it. I fixed the issue to good results.
Tight waistband has also immediately helped my back and shoulders.
But I also gotta say that I carry my daughter on my back for two- to six-hour hikes, and it’s just tough. I find it harder than backpacking because the total weight is more than I typically carry, even for a couple of nights. And she’s not static. She moves her weight in weird and uncomfortable ways. Sometimes it hurts.
