At Hatch, they created a backing material that has the touch and feel of Dacron combined with the strength and diameter of Gel Spun in a single 8 braid PE line for use in all fly fishing applications.
Why only one size backing?
Take a look at the chart below. You’ll see that the diameter of Hatch backing is equal to or less than their competitors’ products. Now look at the lb test ratings. You’ll notice right away that their material is stronger than everyone else’s. The diameter of the line determines how much backing builds up on the arbor of a reel, not the pound rating. So, a single diameter line can be used effectively in all fly-fishing applications – fresh or saltwater.
100m = 108yds .015"dia. 68lb test
200m = 216yds .015"dia. 68lb test
400m = 432yds .015"dia. 68lb test

The 1200m packs are made up of twelve connected 100m interlaced spools. This will allow you to spool up several reels with the lengths of your choice.
