Thank you for the ULA lead! Looks like around 2 pounds(?) and no more worrying about my down gear getting wet, and comes in camo.Been looking for something simmilar:
-Get a cottage maker to make you something in camo xpac from rbtr.
-ULA custom multicam pack
-Kuiu Venture (far from 17 oz, but the additional storage means less stuff sacks and pouches so the weight isn’t terrible). You can also loose the hip belt to shave some more weight, or just start cutting and probably loose a few additional ounces
Those are about the only options I know of unfortunately. As far as hitting your weight goal, I think cottage is your only option.
