What does fly line weight (wt) mean?

Fly line weight (wt) is the sizing system used to identify the line's weight class. You will often see it listed as a range, such as 3-5 wt or 7-9 wt, so you can choose a line that matches the rating you use in the rest of your setup.

How do I choose the right fly line weight (wt) for my setup?

Choose the fly line wt that matches the weight rating you are building around. If you are deciding between options, start by narrowing to the wt range you need (for example 3-5 wt or 7-9 wt) and then compare the item details for each line.

Is fly line backing included, or do I buy it separately?

Fly line backing is typically purchased separately from fly line. If you want backing, look for items labeled as fly line backing and confirm the listed details on the item page before adding it to your kit.

Are leaders and tippet available to go with fly line?

Yes, leaders and tippet are available in their own categories alongside fly line. Many options are labeled with specific lengths (such as 9') or pack sizes, so you can choose what fits your needs.

How should I store fly line when it is not in use?

Store fly line loosely coiled and out of heat and direct sun. Before putting it away, check for nicks or tight coils so it is ready to use the next time you pull it from your kit.
