D of E Bronze expedition - kit list help please!

[TwigTheWonderKid]

DS is doing his expedition tomorrow. Did his practice one in April when the weather was foul and pretty much took everything on the kit list. Weather looking much better this time and as it's a longer walk he's keen to keep the weight of his bag down. However, having just looked at the official kit list I am confused about which items are compulory.

Can anyone shed any light on this please?!

DS only got list out on Thurs evening.
Back from bronze expedition today (Saturday).

His team got to skip bringing survival bags. Trowel is a new one on me (not on our list).
DS didn't bring spare pants or any toothbrush or soap. Slept in his clothes.
The Leader is a Dragon for checking they have waterproofs though -- they needed today. Rained lightly most the day.

I am sure some of the ration packs are recommended by DofE on their website, like the Wayfayrer packs

I used to run DoE. I’d accept rat packs if they could justify the choice and demo nutritional planning/basic cooking somewhere along the line. So, for example, rat packs are fine on gold for two nights out of three.

That was a few years back so things may have changed
