How to pack it all
Check with your troop on the preferred type of pack, but soft packs vs. footlockers are better for packing purposes. Soft backpacks can fill voids when hard plastic cases require plenty of stacking room. Shoulder strap packs are also easier for scouts to carry into camp and on hikes.
In your pack, consider dividing your outfits into plastic bags for each day of the week. They are easier to sort and waterproof. Just like weekend camp, make sure there are plenty of extra socks and an extra pair of shoes for when sweat or bad weather strike.
