Atlas UV Glow Yarn brings classic yarn presentations to life with added visibility, giving drift anglers a reliable edge when targeting pressured trout, salmon, and steelhead. The fat, fluffy fibers trap air and scent, helping yarn eggs and flies ride naturally in the strike zone while the UV enhancement stands out in stained water, low light, and deep runs. Many Great Lakes and tailwater anglers soak this yarn in Mike's Lunker Oil, then tie compact yarn balls or egg patterns that hold scent longer and draw consistent attention through the drift. Each bag packs ample material for multiple rigs, fly patterns, or backups in your vest. Fat, fluffy yarn with UV glow for added visibility in varied water conditions Effective for trout, salmon, and steelhead in rivers and streams Absorbs Mike's Lunker Oil (FishUSA SKU: F10259) and other scents to boost attraction Ideal for tying yarn eggs, steelhead flies, and bait accents 12 ft. per bag Made in the USA
