Features

The Hunter is a camouflage rash guard made with strong and elastic synthetic fabric, ideal for scuba diving videomakers and spearfishermen.

The main feature of the rash guard is that protects from wind and from UPF Ultraviolet rays that are harmful to the skin.

The material is elastic and easily adapts to the shape of the body. It should dress tightly, but must not tighten, so can keep warm. If worn under a Neoprene wetsuit the ability to keep warm is increased.

Can be worn over a solid color wetsuit to use the camouflage effect, or over wetsuit that does not have a chest loading pad.

The chest is seamless and features a soft durable pad that protects the body. Essential for loading the speargun. The rash guard is made of 80% nylon and 20% spandex thick 190 g/m2. Made with anatomical cuts and can be worn in any water sports.
