Amazing what tool advice you can find in Forbes magazine!
I followed their suggestion - how the stylish yacht owner sclepps his tool about - to
www.toolpak.com .
These folks offer a vest, #94350, as well as several 'backpack' type carriers, starting with their original model, #90650.
I have the pack Yanici talks about; I have not found it all that great for my uses.
I do use the carrier Mahlere posted; it works well.
My problem has been more with parts storage, than tool transport- especially when atop a ladder. So far, I have found the Skiller's pants and vest to be great!
