A+ UNI-Thread is made of the same material and construction as 3/0 UNI-Thread but it is much stronger. It is a favorite of saltwater fly tiers who demand a very strong thread to resist the sharp teeth common to many salt water species. A+ UNI-Thread comes in fourteen colours, waxed or unwaxed, and on 50 or 100-yard spools. Available colours are: Black, Brown, Chartreuse, Green, Gray, Dark Brown, Light Blue, Orange, Pink, Light Cahill, Red, White, Wine, Yellow. Please note: To rationalize inventory and distribution, we will offer A+ Thread in a single yardage of 100 yds and Unwaxed only once existing stock is depleted.
