K4 vs K2/K3....real world comparison

[BAKPAKR]

I could just not get past the metal tubular frame on my K3. I sold it and got a K4. I don’t k know that the K4 is “better”, but it doesn’t have the tubular frame.

Is everyone's K4s lumbar support pads stiff to start? Do they eventually break in? Got a K4 this spring and ended up running my K3 all fall because of how stiff/uncomfortable the foam in the K4 was when I took it on a few walks around the neighborhood

I have the K3 and K4. I felt like the K4 lumbar pad was very stiff compared to the K3. Steve with Exo says you need to load it up with 30-40 lbs and put 10 miles on it and the lumbar will break in. I only have a couple miles on mine with 30 lbs and it is still very stiff. Made me take the K3 on my last trip because of that.

I really want to get a K4 but the extra weight cuts for the K4x is just too appealing. Anyone know when it's supposed to be released?

Mark from Exo was saying in another thread that they are shooting for late 2026.
