Rapha, nice but a bit pricey?

I've tried a few different markers on the white to various success. The paint ones work best but run a bit in water.

A few of the fabrics forums discuss removing techniques. I never tried.

At the end of the day I figure function over form and don't regret paying half the price for something that functions just as well as something that cost twice as much.

A lorry once overtook me in the rain and spashed a bunch of black gunk over my jersey. Been in the wash a hundred times since and it hasnt washed out. You need whatever that is made of ;)
