HammerHead Ambush, Spearfishing Rashguards are the original warm-water spearfishing tops, designed by HammerHead Spearguns Founder Kevin Sakuda. 1 mm neoprene base on the chest and back provides warmth and stability for the chest loading pad; preventing the speargun from slipping while loading. THE ORIGINAL WARM-WATER SPEARFISHING TOP that has been worn by tens of thousands of spearos across the globe was developed by HammerHead Spearguns founder and US National Champion Spearfisher Kevin Sakuda especially for spearfishing in warmer waters. The HammerHead Ambush’s revolutionary design creates a stable chest loading pad, capable of handling the stress of loading long railguns. Where other lycra tops loading pads would slip from the pressure of a loading speargun, the HammerHead Ambush’s 1 mm Neoprene Chest and Back provided a stable backing preventing the chest pad from slipping under the force of the speargun bands. This is the first wetsuit top specifically designed for warm-water spearfishing; accept no imitations.
