Glossary: I

BKS suits are made with comfort inserts that are designed to act as ‘hinges’ around your suit, in conjunction with the leather stretch panels. Inserts can feature at the inner arm, groin and back of lower leg as standard. Some designs also have them around the back of the neck and in the chest areas. These are made from a stretch fabric blend of Cordura nylon, Kevlar and Lycra. This gives a high level of tear and abrasion resistance whilst allowing the suit to flex and fold in on itself in the various riding positions.  As an alternative to this fabric you can specify perforated or normal leather instead. Softness is still achieved but the flex is not as good.
