On my old textile clothes from Modeka zero effect, water merrily dripped. I'm betting on a loose weave from use, however, 6-7 years. On the Gloves it was a little better.
Pleasant smell of both products, especially the one for the inside of the helmet. I bought for a new helmet, and refreshed the old one as well. The agent on the outside wears off faster, for the inside it will last longer. I would be happy to buy in a larger bottle, and ideally with microfiber included.
