My wife ran a Kuiu Icon Pro for multiple seasons and packed out elk meat with it multiple times. It did well for her, just never fit her perfect.
When MR came out with womens specific pack, i ordered it for her to test out over summer before this past September elk hunt.
She said really big difference was just the contoured straps fit her just right. So we kept it and sold her Kuiu.
This past September she once again put the MR to real test packing out elk meat. It did well loading the meat and cinching it up.
She said it did well and just fit better with a load because of the contoured straps.
That is our 1st hand experience for her.
