Dynamic Discs BioFuzion Defender - Stamp color will vary. Shade of disc color may vary. For example, yellow can be a mustard yellow or a bright yellow. The problem with the highest speed discs is that they are historically understable. This is no longer an issue. The Defender is here. Fast. Stable. Neither of these descriptions will be in dispute after you unleash this scorcher. You will no longer have to put away your high speed discs when the wind begins to blow. The Defender will have your back when the course and the elements conspire to take you down. Speed: 13 Glide: 5 Turn: 0 Fade: 3 Max weight: 174g About BioFuzion: BioFuzion plastic is created in an effort to make disc golf more sustainable for the environment while still producing some of the highest quality discs on the market. When our production of Lucid or Fuzion discs doesn’t come out to our high-quality standards, they are melted down and combined to create our BioFuzion plastic. This reduces unnecessary waste and lowers disc golf’s carbon footprint.
