La diferencia entre un turtle neck y un mock neck se describe muy bien así: "A polo neck (UK) or turtle neck (US) ... is a garment—usually a sweater—with a close-fitting, round, and high collar that folds over and covers the neck. ...
A simple variant, the mock polo neck (or mock turtle neck), resembles the polo neck with the soft fold at its top and the way it stands up around the neck, but both ends of the tube forming the collar are sewn to the neckline. This is mainly used to achieve the appearance of a polo neck where the fabric would fray, roll, or otherwise behave badly unless sewn. The mock polo neck clings to the neck smoothly, is easy to manufacture, and works well with a zip closure. (http://en.wikipedia.org/wiki/Polo_neck)
Ahora, 'turtleneck' se traduce como cuello alto (como dice Anicasi) o cuello vuelto o cuello de tortuga, pero no sé si existe algo para mock neck, que es una abreviación de mock turtle neck, que toma su nombre extraño, me imagino, de 'mock turtle soup' que es una sopa de tortuga falsa...
En fin, puede ser que no es una diferencia importante y lo puedes llamar cuello de tortuga/cuello alto/cuello vuelto, o podrías agregar 'cosido' a alguno de estos.

They are talking about the sweaters that you can wear under the blazer.
I think you will have an issue regarding the target country, in general they are know as "cuello alto"
