This is a must-have if you are a fan of the layered system for thermal protection. I wear this close to the skin for maximum effect wether it be under an undersuit in the water or for extra warmth in other tech rescue situations. The cost is also a bonus. Great piece of kit.

Recently purchased ND Technical Base Layer

Recently purchased ND Technical Base Layer, first chance today, to use in anger, under my trilaminate drysuit. Water temperature between 17 & 21C, air temperature at end of second dive 28C. Used this base layer with my Lavacore top, using this combination allowed me to drop 2kG in weight carried, compared to my normal under-suit. Felt far more comfortable kitting up and between dives. It certainly did wick perspiration away from my body, which kept me warmer. Very pleased and consider, good value for money, will try under my normal under-suit in colder conditions.
