Kyle Dreger on the GORUCK GR1:
Although the straps took a week to break in, weight from the bag now feels evenly distributed across my chest and shoulders. I can pack the GR1 full with books, clothes, and my laptop, and it still feels comfortable to carry around.
I can vouch for this. They straps are bulky compared to almost every other backpack I have tried, but after a week or so they feel damn comfortable. They feel like they mold to you, to your body, and I haven’t felt that with the other bags I test.
That said there are scientific reasons why such large straps may not be ideal — personally I find most well made bags are comfortable no matter the strap design.
