K4 that doesn’t fit well, trying to decide between IA or SG

[C.F.]

Looking for some input on pack fit and load carry.





I had a K3 that constantly slipped under weight. I’ve been running a K4 for the last two years — it’s better, but still starts sliding once I’m over 40 lbs and needs readjusting about every mile. I’ve swapped hip belts and worked with Exo to confirm fit, but the issue remains.

Previously had a Mystery Ranch, and 30 lbs in that felt like 100 — tons of downward drag.

At camp I tried a Stone Glacier Xcurve with 60 lbs and it felt locked in — zero slip.


Now I’m debating between going with the Xcurve or trying an Initial Ascent to see if it carries heavy loads even better.


5’10”, 200 lbs, stocky build.

Man, if the X-curve already worked, I would get that unless you can try on the IA with weight.

I unfortunately didn’t get a chance to go for A hike with SG it on. But it did feel far more snug and secure than my k4

I think SG has a 30 return window. Buy, go hike heavy, if not happy return and try something else.

I think you are heading in the right direction trying out the stone glacier if it seemed to fit better. For me Exo and Stone Glacier are still by far the top options.

Xcurve is pretty unique frame. Would go with that for sure if it already locked in. i would see if you have friends with either or and test there’s.

I like my x curve, it fits me well and handles weight well. I’ve been using it for like 9 years now. I just got a newer guide 7900 bag for it like ~ 3 years back. It’s been great for me, if you tried one and liked it I’d say that would be a good choice for you.

I used an xcurve for probably 5 years and really like the frame. The problem is the layout of their bags is not what I prefer.

I bought a new pack last year and was deciding between the IA and the Exo. I got a deal on the Exo and went that route. I'm really happy with it.

So, if I were you and the Exo didnt work, I'd go with the IA.

I had an IA and didnt care for it all that much. I have a SG with the Krux frame and love it.

Seems like it's all a matter of preference
