KB Team riders Nathan and Jason have both used the 5/4 Isurus last winter and found it to be a high quality suit and a very warm 5/4. Wider chest opening made it easier to get into than other brands and just started its second season with no leaks.

The suit is equipped with some of the following features:

• Supercharged Compression
• Chest Zip
• Titanium Lined
• Arms Up Design
• KOREgulator Panel
• Bio-Mechanical Lat Panel
• Muscles Stabilization Technology
• Silicone Pre-Tensioners
• Gutter Balls
• Key Pocket
