Initial ascent 3k vs Exo Mtn gear k4 3600 with light load

does anyone have experience with pack comfort with the IA 3k vs k4 3600 backpack with loads under 50 lbs? Thanks.

For sub-50 lb loads, the Exo K4 3600 is more comfortable for long days. The frame, hip belt, and harness are just better tuned for that range. The IA 3K is a good pack, but I found it to be more at home in the 50-80 lb range where the rigid frame starts to pay off.
