I still have a few from more than 10 years ago

no creases whatsoever? no loose waist?

don’t wear the same pair consecutively

how many leggings do you own? because I wear them most days, like 5 to 6 days a week.

would you ask your wife what brands she uses?

leggings are mostly 77% polyester and 23% spandex but there's a mesh segment behind the knees, mesh is 93% polyester and 7% spandex.

I don't know if you're suggesting I cut the legging and make it thinner right below the knees, but this is a structurally very complicated area, as it combines mesh and regular fabric.

Have you ever sewn workout synthetic fabrics? Are you happy with the result?

Switch to merino for active wear and cotton daily to avoid infections.

does your partner hand wash her merino thongs? Merino is expensive and my experience with thin merino garments is they tend to break easily. Doesn't merino itch? Does she have to wash the piece more often than other undies?

I wonder how a full cotton thong would improve my health because so far I haven't had any trouble with my synthetic ones with a cotton gusset. Or does your partner mean full cotton thongs are better than polyester ones with a cotton gusset? Why?

There don't seem to be many brands that market men thongs and strings. Do you find good quality and durable undies for you?
