Lycra on eBay - interesting finds

I bought "Ice Silk" underwear on Ali. It's the most slippery material I ever felt. Far smoother than XKCN / Leohex and it doesn't stretch much. Feels more like non-elastic nylon stockings from the '50s, but thick.

These are more traditional cut and cheaper (6 pack). They're european size and if you're thin and tall you should probably buy one size smaller, because the waist band is the smaller size than the "depth" (waist-crotch-backwaist length).
They are lined in front with a sythetic material that feels like the lining used for swim shorts.

These have a "bulge" cut and I like how they fit better than the other ones, but they are more expensive. Lining is just in front.

So, if you like slippery, this is it!
Unfortunately, "Ice Silk" as a search term returns lots of other materials. I tried to find tights, bodysuits, leotards in the same material - no luck - only leohex-like materials. If you find any, please post here.

Good for you if you like that, but to me Lycra is about the "Holy Lycra Trinity" 
that sort of equally balances visual sheen, tactile smoothness and dynamic elasticity.

So to me the OEKOTEX100 Lycra that brands like Leohex, Amoresy, MJINM and Aesco use:
40 % tactile slipperiness
30 % visual sheen
30 % dynamic elasticity

So, if I encounter a fabric that excels at one of those categories at the expense of another,
the erotic spell vanishes.
