The Men's Flashbomb 6/4 Hooded Chest Zip Wetsuit now includes our E6 Flash Lining that provides 20% more stretch than our previous E5 model, allowing for more warmth and faster drying time. Seams are taped with our E6 Flash lining for extra comfort and water sealing, and our mesh skin panels absorb solar rays and block wind chill to maximize water time in cooler climates.
