I’ve long struggled with how to transport small bits of cables. Since I primarily use the GORUCK GR1 these days, I’ve just been using the internal pockets in the bag to hold cables. This works well, except of course when you want to find a cable.
Often I struggle to find a cable as I buy short and stubby ones to carry with me, or give up assuming I left the cable at home. So I’ve needed a better system for some time now.
