I practice the dynamic apnea for some time and I was looking for a combination to exercise that discipline. After going through several forums and sought advice from several sports friends, my choice fell on the Cressi Glaros and I am not disappointed! It provides a nice smooth ride while having a low buoyancy. Only negative point: water tends to enter the combination by the neck (which in my opinion does not rise enough in the neck). But this is not very troublesome and it takes hours to swim before feeling the problem. I am fully satisfied with my purchase.
