Hareline Uni Single Strand Super Floss

What it is

Uni Single Strand Super Floss is a single-strand fly-tying floss made from 100% rayon in 600 denier. It’s smooth and glossy with a high-shine look, and it’s built to be durable and breaking resistant. On the hook you can lay it flat for broad coverage or cord it up when you want a tighter, rounder wrap.

What to tie with it

Use it for body wraps and smooth body coverings where you want an even, clean surface without bumps. It also works well for quick accent bands and trim wraps, either flattened for maximum coverage or twisted to make a more rope-like segment. Because it’s tough, you can pull it snug to build a firm, polished body.

Flies and the fish they're for

This type of rayon floss is a natural fit for classic wet flies and nymphs that call for a smooth floss body, which are fished for trout in rivers and stillwaters. It also shows up in many salmon and steelhead patterns as a durable, high-visibility body or tag material for swinging in current. On the salt side, floss bodies and bands are common on attractor-style streamers and baitfish patterns for species like striped bass and redfish when you want a clean, bright body section that holds up to teeth and abrasion.
