Upavon Pure Colour Crystal Bugger Chenille is a larger-profile crystal chenille designed specifically for Woolly Bugger bodies, streamer wraps, and predator fly construction where you need the translucent light-catching effect of the crystal finish at a hook-shank-filling scale. The Pure Colour formula keeps color consistent across the spool, and the bonded core prevents fiber shedding under the tight palmer wraps that bugger tying puts on chenille. Works equally well as a body on large wet flies, bass streamers, and pike flies.
