Comfort Endurance™ Suspension Sleeves are made of a higher grade neoprene than most of the Neoprene suspension sleeves available on the market. It is easy to distinguish the higher quality when you take time to feel an Endurance™ suspension sleeve and compare it to others. It has a much smoother feel, and is a tougher and more durable neoprene material than most others. Endurance™ sleeves also have a rugged outer nylon cover. Every Endurance™ suspension sleeve is manufactured using an intensive blind stitching and gluing process that greatly reduces seam failure. With three styles and two stock colors available, there is an Endurance™ sleeve that is right for everybody! Custom colors are also available for an additional charge.
