I use the Freshette--most 'devices' for women are generally the same idea: cup with a tube/hose for the urine. I like the Freshette because it has a REALLY long tube. (Sheesh--that could be interpreted in more than one way
) The tube length (okay, now I'm giggling) is important because you want that pee to get far away from your body--it's also easier to direct than if it were a molded part of the device like most designs. Yes, I have written my name in the snow
Living in snowy climes was actually the reason I decided to get the Freshette--I've had to bare my bum in negative degree weather more times than I like. With the Freshette, it's just zip, stick in the cup and bam--insta-guy!
These devices are also great for the modest person urinating in mixed company. Just make sure the cup empties completely--I did have one 'accident' on a climbing trip. Luckily, I'd made friends with some campers who had an RV and I could shower up. Embarrassing, though.
That being said, I'm a huge fan of these things and recommend them to all women! Quite often, I've seen them come with drysuits.
(Lord help me--after reading through this, my mind has completely fallen in the gutter)
