Welding shirt/jacket suggestions

[Haywire]

I'm looking for a welding shirt or jacket that is durable enough to last yet won't turn my welding practice into a heat stroke risk.

I bought a welding shirt a couple weeks ago for 20ish dollars but am already feeling the spatter get through to my arms.. it's not often just yet, but I know it's only going to get worse and this particular shirt isn't going to last. I've been thinking of getting some sleeves and sewing them permanently on top of the existing ones for a double layer.

Edit... I see they have some with a 9oz cotton torso (what my current shirt is) but with leather sleeves... Then there's also a shirt similar to mine but made with heavier 12oz treated cotton.

thanks,
Ian
