2018 Rd 9: Post Game Calm: Carlton vs Melbourne

[Thryleon]

It's interesting, I'm not sure about the materials or tech in the jumpers today, but back in my day long sleeve jumpers made you neither warmer nor better at marking. The only thing they guaranteed was that in the rain you'd be carrying around any extra kilo or two once they were soaked and covered in mud!

I imagine what they are stating is true of marking a wet footy.

material would add friction to a leather ball making it much easier to catch than wet skin.
