Abstract: Some results are given on the closure under suitably restricted products of a class of spaces similar to one considered by Z. Frolík and, more recently, by N. Noble. An answer is given to the following question of Gulden, Fleischman, and Weston: Does there exist $ \mathfrak{M} > {\aleph _0}$ and an $ \mathfrak{M}$-compact space $ X$ such that some subset $ A$ of $ X$ of cardinality $ \leqq \mathfrak{M}$ is contained in no compact subset of $ X$? It is shown that for every $ \mathfrak{M} \geqq {\aleph _0}$ there is a topological group which has this property.
