Dyneema® Arm Protection is Cool! One of the most distinguishing Dyneema® characteristics is its cool-to-touch property. Dyneema® fiber's inherent ability to dissipate body heat and pass moisture from the inside of the sleeve to the outside results in longer wear time, which promotes greater protection. The 9318D10 is a 10-gauge Dyneema® cut-resistant sleeve and is 18 inches in length. (Also available in vending packaged option - VP9318D10).
