UTC Vinyl Rib is translucent, D-shaped, plastic nymph ribbing material. This half-round material is soft and easy to work with.
The extra small, midge size is great for midge bodies. The small, nymph size is a good material for ribbing and abdomens on nymphs, scuds and makes great bodies on smaller saltwater patterns. The medium vinyl rib is great for hook sizes 4 to 8 for patterns like Crazy Charlies, Gotchas and other saltwater patterns, and the large is best used on size 6 t0 1/0 hooks, for both saltwater and stonefly patterns.
