Scientific Anglers XTS Gel Spun 500 yd Backing – Yellow, 30# | High Capacity & Abrasion-Resistant

Premium backing for demanding anglers

Scientific Anglers' XTS Gel Spun 500 yd Polyethylene Fly Line Backing in a bright yellow helps you maximize capacity without compromising strength. The micro-diameter gel-spun polyethylene used here is engineered to deliver a compact profile that sits neatly on your reel, leaving room for more line while remaining resilient in water.

Designed for diverse fishing environments, this backing emphasizes visibility, durability, and long-term performance. It’s a versatile choice for those who chase big fish in saltwater, or anglers who want a reliable backbone for their reel as conditions change from dawn to dusk.

Why choose XTS Gel Spun Backing

• Up to 75% more capacity than standard backing thanks to a micro-diameter construction
• Retains 100% strength when wet, helping you stay prepared during fights
• High abrasion resistance protects against snags, rocks, and rough environments
• Bright yellow color increases visibility in low light and thick water
• UV, gas, salt, and exposure resistant for varied conditions

Real-world use and pairing tips

In saltwater and big-water settings, the added capacity can help you execute longer runs without re-spooling. The high visibility aids in tracking the line during drifts and retrieves, while the durable composition reduces the risk of failure when contact with structures occurs. The gel-spun material balances a tight diameter with reliable strength, making it a practical option for reels that demand a robust backbone.
