RIO Premier – Technical Euro Nymph Fly Line
RIO’s Technical Euro Nymph line is designed for modern nymph fishing. It features a monofilament core that provides a stiff, slick feel, enabling quick feeding and minimizing line sag between rod guides. The ultra-thin diameter enhances sensitivity and allows for lightning-fast hook sets.
The core extends past the front end to form an integrated leader, eliminating knots that can get caught in guides. The line can be cut to length from the back, allowing anglers to adjust it to their preferred length.
The leader has a diameter of .013 inches and is pink for easy visibility. It is level and can also be cut and adjusted to suit different fishing conditions.

Jennifer Stewart –
This line performs great in dry fly and nymph setups. The sensitivity is outstanding and the integrated leader makes it easy to fish without knots getting caught. I cut it to a 10-foot length for my current setup and it works perfectly.
Zoe Graham –
I’ve used this line for several weeks in different water conditions. The pink leader is easy to see, and the line feels very responsive. No knots to worry about, which is a big plus.
Wendy Fraser –
The sensitivity is excellent, and the line cuts cleanly. The only minor issue is that the leader is a bit thin, so it might fray slightly in rough conditions, but overall it’s a solid choice.
