Recommend Big 3 as “loaners” for Scouts

Part of my Wood Badge ticket will involve purchasing gear that many of our Scouts can't afford for higher adventure trips. I need to focus on lightweight stuff that can take a fair amount of abuse and can be used year round preferably and for many years to come.

What would you suggest for the Big 3 to supply the Troop's "loaner closet" in this case? Bags should be easily washed so does this eliminate down??? To make it more challenging, let's say you can't spend more than $200 for a set (THAT likely eliminates down – LOL). Can it be done without MYOG or buying used? If not, what's the best you can do?

Thank you for your advice.
