Okay I can't tell you that sure does remind me of the NRS skull cap that is WAY $$$ higher...I can't because that would be false advertisement...they aren't even the same product. But you could get that...or get this one...and have some money left to go boat with it.

From Level Six

Based on the same pattern as our full coverage Block Heater, the Skull Cap fits easily under your helmet for a comfortable thermal layer on your head without the added bulk of a chin strap. The Skull Cap is constructed from our signature Micro Plush neoprene that features an inner layer made of thousands of soft nylon loops for an extremely comfortable fit with next to no chaffing.
