In contrast to the men who pee discreetly in every second hairpin bend, as a lady you have to think a little longer about whether it's really that urgent to do it now. On the one hand because of the inevitably laborious peeling out of various layers of clothing, on the other hand, and of course there are different sensitivities here, because the whole thing can't be done so discreetly. A ski tour colleague once confirmed to me that he only pees so often because it's so easy.
On tour with a ski friend I greatly admire, one day I could hardly believe my eyes - had she actually just peed standing up - totally discreetly - without pulling her pants down? Just like the boys? Yes, she had. And with the help of a platinum funnel. The thing is called WhizFreedom and is purple. I bought one on the strength of my girlfriend's convincing recommendation - "it's practically changed my life". We agreed that trying hers would have been going too far.
The WhizFreedom is a simple funnel. There are various similar products from other manufacturers, all with similarly great, haha-funny names: Freshette, Urinella, GoGirl, SheWee. There are both disposable funnels (usually made of cardboard, found at festivals, for example) and the plastic version for multiple use. The latter are usually made of hydrophobic material to prevent the potential Igitt factor. Of course, you should still wash them regularly. Some models have a small extension tube, such as the "SheWee Extreme". Many manufacturers rely on purple to pink shades, but other colors are also available.
