Try stuffing all the standard pack into the old field pack... I remember that before i going for my 24km route march,the nite before the march,had the field pack until nice nice then PC say field pack inspection,we all sian half but the good thing is the nxt day other platoon having their check,we are not doing it... Had a hard time stuffing my PT shoes in them... Kan hard.... With the new field pack... Confirm extra things inside wan... the webbing the new wan is def is better than the old wan... The old wan(we call it bra),the bra strap keep on falling,gotta black tape them all the time...
actually black taping aint enuff for the old one
i always use cleartape..tape tightly
then i black tape over...
