Men's 5/3mm Henderson Aqua Lock Hooded VestThe 5/3mm Men's Henderson AQUA LOCK Hooded Vest helps form a seal against cold water. This hooded vest was designed with extremely soft and flexible AquaSilk neoprene laminate. A great feature of this hood is the liquid taped AquaLock seams. Every seam on the suit is sealed inside and out, then coated with a waterproof liquid tape that prevents water entry while ruggedizing the seam. The interior jersey is lined with a golden microfleece lining which wicks moisture from the skin while retaining precious body heat. The 5/3mm Hooded Vest features an Aqua Lock seal around the neck opening for easy pairing with any Aqua Lock fullsuits. Other features include: a contoured chin cup for extra comfort, and a flow vent on the hood to purge excess air.
