Vermarc are fine, but far from spectacular, and often overpriced, in my opinion.

The lycra is decent enough, but I've had more comfortable; I find the older Nalini lycra much nicer and more second skin-like (however, the last time I tried on some Nalinis, the lycra, cut and chamois seemed to be different).

And the Vermarc chamois is a little on the thin side for me -- they feel find for the first few weeks, then seem to compress down to not much.
I much prefer Ellegi chamois.
