SINK TIP FLY LINE

Sometimes, the biggest trout live where backcasts aren’t your best friend. Sonar Trout Express has a short, rear weighted head that excels at roll-casting large streamers in tight spaces.

Formulated with Advanced Shooting Technology
Extended rear taper stabilizes longer casts
SD Blend technology for the smoothest possible transition between densities
Sink Rate: Floating running line, intermediate belly, Sink five tip
Braided multifilament core
SA ID – SA SONAR TROUT ###GR F I S5 (### = grain weight)

Formulated with Advanced Shooting Technology
Extended rear taper stabilizes longer casts
SD Blend technology for the smoothest possibe transition between densities
Sink Rate: Floating running line, intermediate belly, Sink 5 tip
Braided multifilament core

AST patented dry-slick technology provides continual line slickness, allowing the line to shoot farther as it moves through the guides. Lines with AST easily shed dirt, algae, and other parasitic drag particles, allowing lines to cast farther, float higher, and stay cleaner than traditional lines.

Built from the specifications of your selected option and validated by Stillwater Fly Shop staff.
