The first series of lines to feature the revolutionary AST PLUS slickness additive, the Amplitude series will shoot farther and last longer than any other line on the market. It’s slickness down to a science.

The conventional wisdom in fly fishing is that there’s no such thing as a “do it all” freshwater line. We have something to say about that. The Amplitude Infinity has the power to bomb out streamers, yet retains delicacy for dry flies. It mends like an absolute dream, and delivers flies at all distances. Built a half-size heavy, with a long head and substantial front taper, it’s perfect for everything from trout and panfish to pike and steelhead. There’s a reason we call it the Infinity: there is no end to what you’ll be able to do with it.

  • Features the revolutionary AST Plus slickness additive for superior shooting ability and increased durability
  • Floating Texture on the tip section for the ultimate in flotation; it simply keeps dry flies floating longer
  • Shooting Texture running line delivers longer casts, thanks to a reduction in friction
  • Extremely versatile general-purpose taper designed for most freshwater species; an excellent line for trout, grayling, panfish, bass, carp, steelhead, salmon, and pike
  • Made a half-size heavy to load fast-action rods, but works well with a variety of rod actions
  • Extended head length for long-distance casts and superior mending ability
  • SA AMP INFINITY WF X F (X = line weight)


When Canada Post lost my package, the guys at Drift Outfitters honored the sale and sent me a new order the next day. It's nice to deal with a company that has great customer service.

Dope fly shop, crazy selection of flies including big topwater bass flies of all sorts, and big pike flies which are pretty hard to find in person. Chill staff, loads of inventory. I make a point to stop here every time I'm in Toronto!

This is the best fly fishing store I have frequented in my 30 year fly fishing experience. The owner Rob, store manager Chris and the rest of the team are very knowledgeable about products and local fly fishing locations. They will guide you towards best products for your needs, and will not try to upsell if a lower priced option is better for you...

Simon Chapman

If you are in the GTA Drift is the only fly shop you need. They have an insane amount of quality tying products, packs, waders, boots, rods and reels. They also have the best staff w/ a staggering knowledge base.
