Meh. I think that one is too bulky. I once bought the braided line that is made of bungee-like elastic, and it was useless. It did not grip the clothing. I really like my braided one that is made of latex tubing. It grips the fabric well. I also take a length of thin cord (like "parachute" cord), because invariably, the braided line is too short to reach between whatever purchase points I locate. To be honest, you could do worse than to use just some cord and pack maybe 4 plastic clothes pins (or a few black "binder clips"). You don't necessarily have to peg every item -- some can just be draped over top. I often use hangers and hang the hanger on the line to save space. Sometimes, for faster drying, I will use 2 hangers to, let's say, hang a top, separating them by a few inches... that way air flows between the two layers (front and back) of the fabric, effecively halving the drying time.
My undies (nylon, and have a cotton lining), I hang inside-out, so that the cotton dries better. Sometimes, just over a chair or door knob.
I have a couple of suction cups that I will use with this, also a couple small caribiners, so that I have multiple methods of attachment.
I do find, though, that I've been using hangers more and more. I pack a couple with me, so that I can make sure they can be hung outside of a closet. I've even hung them over an a/c unit, suspended by a binder clip from a (very secure) window valance. Also, from a ceiling fan! LOL.
FYI, those hotel hangers that just have a nub at the top, that attaches to the metal part that stays on a rod??? You can feed that nubby end through the latex braid, and it will "grab" hold of it, too! So, they can be used outside of the closet to hang stuff.
I sink-wash every. single. night. Sometimes it's just socks and undies, and (at the risk of sounding gross) only the dirty/smelly parts of tops/pants. Yes, I will turn my top inside out, gather the under arms together and wash that section only under a tap with soap. Then twist just that section in a towel, then hang to dry. My point is, you can hang stuff just about anywhere when you don't have a whole "load" to deal with.
