Key Features:
1. Material

Loon Outdoors - Deep Soft Weight Soft Putty Moldable Tungsten

– Made from tungsten, which is denser than lead, allowing for smaller, more compact weighting.
– Non-toxic and environmentally friendly (lead-free).

2. Soft & Moldable
– Easily shaped by hand—pinch, roll, or wrap around hooks or tippets.
– Stays pliable underwater but adheres securely.

3. Deep Soft Weight Formula
– Softer than standard tungsten putty, making it easier to mold and reposition.
– Ideal for adding subtle weight adjustments to flies.

4. Versatility
– Can be used for:
– Nymphing (euro, tight-line, or indicator rigs).
– Streamers (weighting heads or bodies).
– Adjusting depth quickly without retying flies.

5. Colors
– Typically comes in dark gray/black to blend with flies.

How to Use:
– Pinch off a small amount and roll into a ball or worm shape.
– Wrap around the hook shank, tippet knot, or fly body.
– Press firmly to ensure adhesion (won’t fall off easily).
– Reusable—remove and reshape as needed.

Advantages Over Lead:
– Denser: Less material needed for the same weight.
– Eco-Friendly: Safer for waterways and wildlife.
– Adjustable: Add or remove weight on the fly.

Where to Buy:
– Sold at fly fishing retailers (e.g., Orvis, FlyShack, local shops) or online (Amazon, eBay, Loon’s website).

Alternatives:
– Tungsten Beads (for permanent weighting).
– Split Shot (less precise but quick).

This product is great for anglers who need customizable, non-toxic weight in their setup. Would you like tips on specific applications?
