The 5.5m gloves worked perfectly in 55 degree water. My hands were never cold. Plus, the gloves were flexible enough for me to effectively spear fish and handle gear in the water.
The standard dive gloves are well made. I've had them for quite some time and they have not lost elasticity. Most degrade within a few months. These have not. Plus they are reinforced in areas where necessary.
I highly recommend both.
