Made 100lbs feel like 50 on my f7 kite.
Great job on making these shoulder straps so comfortable.
I packed 3 miles with 80#s and my shoulders felt great...my legs were not as happy as my shoulders.
It is what you need.
My pack usually runs ~70 lbs. The factory straps were cutting off circulation to my hands, so I bought these. This was probably the best $30 I spent in 2020. All their packs should come with these straps. You should get them immediately.
Love the waist belt and shoulder harness. Much more comfortable than the ones that came with the mainframe. Makes packing heavier loads incredibly easier. My only complaint is that these weren't already on the mainframe, but for the price you can't go wrong. I will still be a loyal costumer.
