Oversized loops
Give the eye of the fly enough room to use a heavy-duty bite tippet, and creates space for bigger hooks (6/0 or 7/0) to move freely on the back loop.

Extended loop length
Allows you to tie them down further along the shank, which adds strength to the loop and helps prevent bigger fish pulling out the loop during an extended fight.

Stainless steel
For use in saltwater streamers.
