So i currently have a Kifaru 22 MAg. I like it and think it carries weight well. BUT...... it seems heavy when empty. Really can support heavy loads but i would really like a lighter pack. The other thing i am not a fan of is how hot and sweaty my back gets. Anyone else have similar experience with the 22 Mag? Any tips on a lighter set up or do i just need to pack shop? Im not fully versed on all the Kifaru option and yes calling them will be my next step but i thought i would ask here on peoples thoughts
