Acerbis Rain Pro 3.0 Clear Jacket

Worn over leather jacket in January. Heavy rain and was completely dry . Kept wind and rain out and a good fit

Same sort of material as a lilo, neoprene neck & wrists are quality, zip is good, excellent wind cutter, as close to waterproof as makes no difference bar the ventilation down the sides but you need some ventilation it does hold heat, you can steam up in there.
Keeps the mud off your clothes & easy to clean..
Size wize a small/medium would easily cover a large bomber jacket & be hanging well below it to give you an idea.

I especially like that it clear... Worth the money !

my textile jacket isn’t fully waterproof anymore and takes ages to dry out this over coat keeps me 100% dry even in very heavy downpours

Purchased for an EU tour. Had to use it on 2 of the days and worked a treat. Still can see my HiViz under it and folds up nicely in the rear pocket of my Revit Samd 4 Jacket
