My 13 year old is not unusually small, but he is only 155cm and 43kg, so about the size of a 12 year old. He will be doing his DofE practice expedition in March. He has plenty of experience of hiking and camping with Scouts, and did his Scouts expedition challenge (similar to DofE expedition but only carrying day packs) when he was 11.
I'm worried about him carrying a full size trekking rucksack though. Is there a maximum percentage of his weight he should be carrying? He already has a 65 litre DofE recommended rucksack but has only used it for Scout camps where he hasn't had to carry it far. Would this be too big?
Does anyone else have a small teen who has done the DofE?
