RIO Products Euro Nymph Shorty Fly Line #2-5 20ft Floating Orange/Sage/Olive Review (2026)

What the Shorty actually is

RIO built the Euro Nymph Shorty as a short, ultra-thin, low-stretch segment of line rather than a full fly line. At 20 feet long and rated for 2 to 5 weight rods, it is designed to be added to the front end of a standard floating trout line using welded loops on both ends of the Shorty. The idea is that an angler can fish their normal setup for most of the day, then loop the Shorty on when they reach a run they want to fish with tight-line nymphing technique, and remove it again afterward to go back to a normal floating line setup for dries or indicator rigs later in the same outing.

Construction and colors

The Shorty is built on a low-stretch core with a level taper along its full length, which keeps the diameter thin and consistent so it transmits strikes clearly without the taper changes found in a standard fly line. RIO finishes it in an orange, sage and olive color scheme, a combination intended to help anglers track the line and detect subtle takes at close range, which matters since most of the visual bite detection in tight-line nymphing comes from watching the line rather than a strike indicator. The line carries a listed price of around thirty dollars, positioning it as a lower-cost entry into euro nymphing gear.

Why the short length matters

Because the Shorty is only 20 feet, it is too short to cast on its own the way a normal floating line would be; it depends entirely on being paired with mono running line or a standard fly line behind it. This is a deliberate tradeoff, since a full 90 foot dedicated euro nymph line requires backing capacity and a separate reel spool, while the Shorty lets an angler add nymphing capability to gear they already own without a full line swap or second reel, which can matter for anglers who only want to try the technique occasionally rather than commit fully.

Setup requirements

To use the Shorty as intended, anglers need a fly line or running line behind it with a matching welded loop, plus tippet and typically weighted nymphs or a euro nymph leader ahead of it. It is not a complete leader-to-fly system by itself, so buyers should plan on adding tippet material and flies, and should confirm their existing fly line has a loop or can be fitted with one to connect cleanly to the Shorty's back loop before heading out to fish it for the first time, since a poor connection at that joint can cost a fish on the hookset.

How it compares to full euro nymph lines

Within RIO's own euro nymphing lineup, the Shorty scores below the brand's full-length 2-5wt Euro Nymph line and its FIPS-compliant version, both of which are built as complete 90 foot lines rather than an add-on segment, and it also trails Cortland's dedicated mono and braid core euro nymph lines in the same comparison. Its appeal is specifically for anglers who want an occasional or budget-friendly way to try tight-line nymphing without committing to a full second line and reel spool, making it more of a starter accessory than a long-term dedicated nymphing setup for serious competition anglers who fish tight-line techniques on most outings.
