Veevus threads are some of our favorites, and their 50 denier gel spun is no exception. This is the perfect thread when you need a strong thread that has very little bulk. Gel Spun threads are incredibly strong and perfect for deer and elk hair, as well as any other time you need a strong thread. If you're tying Elk Hair Caddis, Stimulators, or Humpies, this is the thread you need!
