My son just passed selection, and I promised him a rucksack if he did. I have looked at the different sites talking about the best brand name kinds, but what I would like to know is how many rucksacks do you own that you have used on the job, and how many liters or cubic inches does each one hold?
I realize it would depend on the job, but I am guessing that there is one backpack that you used the most. Which size one did you use the most? My son starts 18D training in March. Thanks for any information you can send my way.
