Pro Floss 340 Den
Our Pro Floss 340 Den is completely unique and unlike anything currently available on the market. A versatile material that can be used for ribbing, tags, collars, and posts on trout nymphs, wets, dries, emergers, and small streamers. The larger size is best for larger nymphs like stoneflies, big dries, and streamers.
One of its key attributes is its great binding strength, making it easy to grip materials and hold them securely in place.

I’ve used Pro Floss 340 Den on several trout nymphs and it holds the materials securely. The binding strength is excellent, especially when attaching small components like tags or collars. It’s a reliable choice for both dry and wet flies.

The floss is strong and easy to work with. I used it on a few streamers and found it holds well under tension. A bit more expensive than other options, but the performance justifies the cost.

Great for adding structure to my emergers. The material doesn’t fray and stays in place even during long casts. I’ve been using it for a few weeks now and it’s still in great condition.
