How would I make a script to equip a vest with a tool?

So, I have a tool and a vest in a folder called Vests in ServerStorage. I want it so that if you click with the tool equipped, it'll put the vest on the player. The vest is called SBAV, it's a meshpart. Here's the script:

local Vest = game.ServerStorage.Vests:WaitForChild("SBAV")

function onActivation()
local g = Vest:Clone()
local C = g:GetChildren()
for i=1, #C do
if C[i].className == "Part" or C[i].className == "MeshPart" then
				local W = Instance.new("Weld")
				W.Part0 = g.Middle
				W.Part1 = C[i]
				local CJ = CFrame.new(g.Middle.Position)
				local C0 = g.Middle.CFrame:inverse()*CJ
				local C1 = C[i].CFrame:inverse()*CJ
				W.C0 = C0
				W.C1 = C1
				W.Parent = g.Middle
end
				local Y = Instance.new("Weld")
				Y.Part0 = onActivation.Parent.SBAV
				Y.Part1 = g.Middle
				Y.C0 = CFrame.new(0, 0, 0)
				Y.Parent = Y.Part0
		end

		local h = g:GetChildren()
		for i = 1, # h do
			h[i].Anchored = false
			h[i].CanCollide = false
		end

end
onActivation.Activated:Connect(onActivation)
