The Amplitude Smooth series of lines are, simply put, the highest-performance smooth fly lines in the world. With up to five times less drag and eight times the durability of traditional lines, this will change the way you look at fly line performance.

If you’re anything like us, the allure of big fish and big rivers is intoxicating. That’s precisely why we created the Amplitude Smooth Anadro/Nymph. Designed with line control in mind, its extended rear taper allows you to cast a mile, mend with authority, and turn over nearly any rig imaginable—from dredging double nymphs to larger dry-dropper concoctions. Steelhead, salmon, and trout won’t know what hit them.
