Low stretch performance in a lightweight line.

Created for performance-oriented cruisers and casual racers wanting higher strength and lighter weight than that found in polyester double braid. Like Samson’s competition-grade line, XLS Extra-T offers the smooth flexibility of a 24-strand braided polyester cover with a braided core made from a blend of MFP and SK-75 Dyneema®. The blended core offers the strength and light weight of Dyneema® fiber for performance without the high price of a 100% Dyneema® core. Cover Fiber/Construction: 24-strand polyester. Core Fiber/Construction: Multi-Filament Polypropylene (MFP)/Dyneema®. Stretch: 1.0% at 20% of breaking strength.
