Extended Velcro® fastener reaches right to the bottom of the throat. If you have a large or a slim neck, you can adjust a comfortably snug fit that properly keeps out water.

The inner surface is lined with FIR nap. Recycling heat that would otherwise be lost, from escaping body heat, FIR nap generates far-infrared heat and keeps you warmer.

A 20 cm long (4 cm longer than average) fastener at the wrists provides ample sleeve opening. Generous 16 cm zips also ease entry at the ankles. With the provided strap, you can pull the back zip up and down using one hand. This strap has also greatly improved fastener durability.

On the outside, the surface is covered with Inospan jersey, which has superb durability and more than five times the stretchability of normal jersey.

Good at shedding water and keeping the wind out, on land and underwater, this snug material achieves outstanding high heat retention. It is also very stretchy and easy to get into and out of.
