Garden Flexible drainage pipe & fleece?

I take it from the mm that you're not living on the same country as I am. That's ok. Here's what I do, I take either a three or four inch pipe and what they sell to put over it is a fabric, but not fleece. I would think fleece would deteriorate sooner than the cloth I buy. I went on the net to look at the conversion and on inch is equal to 25.4 mm. It appears that your pipe is not large enough for a drainage pipe. Do they sell 75 mm and larger pipe. The pipe you're buying will not carry much water away. If you cannot find the pipe anywhere, what size can you find? I do this type of drainage all the time.
