Looking at getting a PLCE Bergen for my daughter to do her DofE Gold ( we have had 3 rucksacks so far , to do her Bronze and i think its time to get the best ), the gold is 3 nights away, so she will need to carry a fair bit of stuff

I have messaged the few army mates i have, one replied about getting a large hiking backpack from a camping shop ( we have done that before and it hasnt worked out well )

SO short or Long ? ? ??
