these have a 100% cotton 'wide crotch' as they put it!
'Wide' how unkind! It's just normal width we're after, not some skimpy narrow strip!
I find them very soft and comfortable - and not in the least 'Nylony' - I think the word Nylon has put people off. They get 4.5* reviews on the JL website.
Anyway, I've ordered six more pairs as they're reduced - so will have four ivory and four black. I'll now chuck out the M&S Flexifit knickers that I bought last year as they all gone very baggy around the legs.
