good question i was wondering the same thing. I would also like to piggy back this question I am about to make a down top quil and i thought while i am at it make a foot under quill for the nx250 using the area with velcro. but my question is redaring the rest of the back area and which would be best. should i make a full bottom under quill attaching at the velcro at the feet and on the sides where the pockets do not conect completly or do i just do the feet and make squares of down to fill each pocket individualy? i will be using this system for a thru hike this summer and will be putting my gear in the pockets at night.
any thought would be great. and bradley do you have any pics of the pads you put in the pockets themselves?
